Hey guys, I was just wondering if anyone here collected coins. My brother, and my dad, and I all collect coins as a side hobby. What coins do you collect? What types do you have, and the oldest ones? I have many books for nickels, dimes, and pennies. I just love the feeling when I can open up the book and find it full! My brother and I just bought some old Indian Head pennies, as well as some Steel Pennies from 1943. (During WWII) I have many foregin coins, as well as about 20 Susan B. Anthony's. I have about 10 Sacajawea coins, and a few Kennedy Half-Dollars. I just love the feeling of the profit that will be made in the future. Today I collected about 6 brand new 2007 Pennies, and took them out of circulation. Share your tips, tricks, and cool places to find your coins! As well as your coin collections!

Hey Guys... don't know if I posted with the right category, so i'm open to corrections. ... Need advice in the process from Coin Slot to Coin Segregation to Coin Dispensing, especially Coin Segregation and Coin Dispensing. ... From insertion of coin, Coin Segregation will take place, which will then put individual coins to separate casings. ... and from there Coin Dispensing should be available for each casing. The logic for dispensing would be "1 click to 1 coin dispensed" . ... already have an idea on separating each coin from one another upon insertion in coin slot and then to coin casings. ... the problem would be is on the Coin Dispensing, need help and ideas. Thanks if replied/answered.

This is my knex coin pusher. before you start begging for instructions i dont know if i will post but if to many people struggle to build one i might post instructions, because im not posting instructions i have taken extra+ photos of the mechinism and how it works. i had to use white connectors because i didnt have enough coins, if you do this the connectors wont fit down the slots so you have to just place them. i would make a video but the batteries in the moter died. it has a secret gutter on the side that real coin pushers have and the monney goes to the owner of the machine, if you dont want this you can push the orange connectors on the right down and it blocks it out. this one is bassed on bezempje95 link to his one http://www.youtube.com/watch?v=5dOPa1-zDUI he has more infomation on his in the link in the description.(if you havent looked at his you need to because its so awesome). if you cant build it from the pictures put a comment saying: "POST +1" with the capitals and if it gets over 15 before christmas i might post it.

Hello, I have a 50 pence coin that I noticed because it was not accepted in a vending machine. On comparison with another coin of the same year it became obvious that something was awry. I don't mind because I like fake coins, they are interesting. It is noticeably thinner and at least a gram lighter; it just feels less substantial. The rim on the upper half of the coin on both sides has either worn away or was never there. I looked on the Googles but can only find information on counterfeit pound coins, of which there are millions ( between 1:50 and 1:200). It seems that a 50 pence may be too low in value to fake. Are there any coin collectors out there who know whether this is likely to be a fake coin or an error coin. If it is an error coin does it have a value. Thank you. PS Through reading around, I discovered that the 50 pence is a special shape; despite its odd shape it has a constant diameter.
Question by FriendOfHumanity | last reply
I'm trying to build an electrically controlled coin dispenser (all the coins will be the same type). I have a metal tube -just the right diameter for the coins - mounted vertically, with a piece of wood horizontally at the bottom. There is a gap between them of approx 1mm, just enough for a single coin to be visible. I've been experimenting with using a solenoid to swipe a coin from the bottom. Rather like the image here: https://www.instructables.com/answers/Petty-Coin-Bank-Design-Coin-Dispenser-What-shou/ Solenoids aren't cheap, and I was aware that the weight of the pile of coins (I'd like to be able to hold around 100) would mean it needed to be fairly powerful. In the end I bought some cheapo solenoids from ebay (around $7 each). They are rated 2A and have a hold force of 20N - this seemed a lot more powerful than I could find elsewhere for even 10 times the price. Given how cheap they are, I could even use two in parallel if I still need more power. I'm using coins with a 20mm diameter, but after the solenoids arrived I realised they only had a 10mm stroke - obviously not enough to fully push the coin away. I've tried using the solenoid to pull a lever, but this doesn't seem to work very well. Previously I'd also tried a stepper motor linked up to a disk with a coin-sized hold cut on it, rather like this: https://cdn.instructables.com/F49/GK0I/H703O9VD/F49GK0IH703O9VD.RECTANGLE1.jpg That worked pretty well but was very slow - it would take 3 or 4 seconds to dispense each coin. So, I'm looking for a bit of advice. Would I be better off splashing out on a more expensive solenoid with a 20mm+ stroke? Am I approaching it the wrong way?

So my friends and I are planning to sell, well...things (I'm not going to give out any details as of now, later) that incorporate small round metal disks. now in all of our prototypes weve used coins for our purposes and they work great. but for what we make we need to cut and sand coins in different ways. and my friends always tell me "its illegal to change money in any way." But I've heard that its only illegal to modify money to change or duplicate the amount its worth - like making a penny into a dime is illegal but making a penny pac man figure isnt. can anyone clarify this for me? I'm fine doing illegal things like modifying coins for personal use but if were going to sell these I want to be a little more clear as to what is going on.

I want to create a PS2 (slim) based fee paying game room for kids, but I want to make it coin operated. I want to use a MOSFET transister switch like this one http://brunningsoftware.co.uk/FET.htm which also doubles as a timer. The coin handling mechanism is the easy part, so dont bother about that.My problem is where to connect the MOSFETswitch in the PS2 console. My first idea was to connect one switch to each of the controllers ( to enable/ disable the controller's power supply on pin 5) but I understand the controller port is part of the PS2 motherboard and new electronic components cant be fitted there (true or false?). If true where else can I fix the switch in such a way that when a game is finished a new game cant be started without feeding in a coin?Any Ideas?

Hey people! So I am making a project, it count's coins via arduino. So I need a way the coin can touch a button or some sort so it can trigger a the code in the arduino. See, the arduino has 4 buttons each one is a value to a coin, in the real world (physical project) there is a coin which falls from a sort o slot. It falls straight. The question here is, how to trigger a type of switch, button, tab with only the force of the coin. Any ideas for buttons or tabs or switches or metal contacts please, thank you. Some kind of easy input sensor (maybe light sensor?) It has to be cheap and it has to be small.

I think i may of coined a phrase, but of course I can't prove it " Its funny cause its true" I even heard it on TV the other night, I have been saying that for years. Anyways today after a student made a mess I gave him a mop and bucket and told him to clean it up. After 20 minutes I came back and he had managed to make the mess about 100 times worse. I was very annoyed with him and I was inspired to say "Never send an idiot to do a job a monkey could do" Anyway there is, If it takes off I will now have proof that i said it first on 20 april 2016 So whats your favorite phrase or one liner?

Hello all, could anyone give me some insight to how complex the process of designing a very small GPS tracker which could be used to track lets say a person, which can post its co-ords to map software which is custom programmed etc in realtime. Hypothetical scenario: 1) Tracking someone who is on the move outdoors, only has very small pockets to fit the thing in. 2) The device must send co-ords to mapping software on a computer every 10 seconds maybe. 3) Someone can view there position on the map software in instantly to understand their exact position. Also how expensive would the whole process cost to manufacturer roughly? Thanks in advance and sorry for the vagueness in my question

Saul heard about this sweet idea at the G4G8 conference. It's perfect for an Instructable - hopefully someone is suitably inspired to do it.Take 40lb's of pennies. Drop them all (equivalent to tossing). Collect all those that were heads and put them back in the bucket. Drop them all again, again choose all those that land heads. Repeat until there is only one coin left. This is the luckiest coin in your bucket. Apparently, one guy got a coin that tossed 17 heads in a row...

Acoustic method could quickly catch counterfeit coins.You might assume that counterfeiters only bother with high-value bank notes, but there is a chance that some of the coins jangling around in your pocket right now are fake. If Mototsugu Suzuki gets his way, it may be that jangling that gives them away.Suzuki, a researcher at the Tokyo Metropolitan Police Department's Criminal Investigation Laboratory in Japan, has developed a way of examining coins based on the sound they make.In Suzuki's method, coins slide down a slope and then fall onto a brass block. The sound they make on impact is relayed via a microphone to a computer.Although the human ear cannot usually tell the difference between real and fake, a computer can. Genuine 500-yen coins showed four distinctive peaks of natural resonance frequencies in the 5-20 kilohertz range. This was not the case for fakes; some fakes produced only three peaks, while others showed four but at different frequencies to genuine coins.In addition to helping detect counterfeits, the sound data could be used to build up a database of fake coins, suggests Suzuki. This might help law enforcement officers to prove how many coins one counterfeit operation is responsible for. This would make for an awesome Instructable! Start with these two Instructables and get dropping pennies! https://www.instructables.com/id/Build-a-dsPIC-Oscilloscope-and-Spectrum-Analyzer-/https://www.instructables.com/id/Low-speed-AVR-oscilloscope/

Need help finding a particular instructable, friends. I would almost bet body parts that I saw an instructable here that had the following process to it for making a custom fantasy coin or medallion: Use the underside bottom of a paper coffee cup-mix up a portion of Bondo and fill the bottom recess with it. When Bondo hardens, pop out the round disc, paste a paper disc onto it then draw out your coin or medallion design. Carve out your design with a dremel or similar, make a silicone putty mold, then when mold is dry, pour pewter or zinc to make a custom coin. Darken and polish. I know I've seen it, I'm wanting to stick it in my favorites list so I don't lose it again, and I especially want to thank the author for coming up with such a simple process for a custom medallion.

Hey Guys... need some advise and help on the initial idea and components of this project. PETTY COIN BANK: PURPOSE: - To electronically segregate coins, display the total number of coins per each case and the total monetary amount inside, with dispensing and security capability. FUNCTION: - Individual coins inserted in the coin slot will be segregated to go to the corresponding individual coin cases and each case will count and display the number of coins dropped in them and a general display for the total amount of money inserted in the device. With a security lock, the device is capable of dispensing coins. so What do you think? Some advise on how i can make this possible... I do have some ideas on the segregation and dispensing mechanisms of the project, and how to identify each of the coins from each other when inserted in the coin slot.My concern would be the Displays for the each NUMBER OF COINS that falls per case (3 displays in total), and the TOTAL MONETARY AMOUNT display that counts per inserted coin in the system. Of course when dispensing, the number of coins should be decremented and the TOTAL MONETARY AMOUNT would change as well depending on the coin and number of coins dispensed. And as you might have read from the purpose and function, this project intends to have a security lock for the dispensing mechanism. Anyone can put coins but only someone that knows the code can dispense coins. I plan on putting a keypad for that. but here is the thing... I DON'T KNOW WHAT MICRO-CONTROLLER I SHOULD USE. I plan on using ARDUINO, but what arduino should i use? and if someone can help i'd like a count of the inputs and outputs so i can decide on what to use. Thanks if someone helps on this...
