Coin Collectors

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!

From Coin Slot to Coin Segregation to Coin Dispensing, Help?

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.

knex coin pusher

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.

Counterfeit or Error coin? Answered

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.

Electronic coin dispenser

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?

coin modifying laws?

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.

Coin operated PS2?

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?

Coin sorter, how to get a coin to trigger a sensor (buttons)? Answered

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.

Coin a phrase, or one liner

Have you ever wonder were, phrases come from like  " That's what she said " or  "See you later.......not if I see you first" or "Well, there's your problem!" 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?  Maybe you could come up with the next "That's what she said!"

How to make a super-lucky coin

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...

Help with a cast metal coin instructable!

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.

How to modify chargers for coin cells?

Hi. I'm wanting to modify one of these drone charging cables to work for lithium rechargeable coin cells (as small as 1220). I'm assuming I need a resistor? But what size and where do I add it? Would I need to replace one on the board (they are VERY small), or could I add it where the cable wire is connected to the board since there's plenty of extra space and I wouldn't need to use an itty bitty one? The boards are both blank on the back sides. Any help would be amazing. Thanks!edit: I also found a little green board.Maximum charging current : 1000MA Full charge voltage : 4.2V+-2%Photos added.Would this one on aliexpress work for 1220, or would it be too much since it's made for larger?

Coin Segregation Designs - Can anyone Help?

Hey Guys... Need your advise on this. from coin slot to coin segregation, so what do you think? - I plan on using ARDUINO UNO - Mainly i have thought of 2 Designs on how to do the separation of coins when it comes out of the coin slot. I have included images so you can see the my ideas. - for the 1st one (three shutters in alignment with the path of the coin), when a specific coin is detected the corresponding shutter will open. - for the 2nd one (using One Motor), when a specific coin is detected it rotates to a specific and programmed angle. - p.s. it would be most efficient if anyone can suggest how can i make the shutters in the first design reverse rotate to set it back into position. - What do you think is more Economical, Efficient, and above all much easier to do of the two? - Need your suggestions/advise/comments/recommendations on this. What do you recommend on the 2 designs? - if so, what motors can i use?

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
