I have a very good coin collections my father left me. I'm not really into coins, and would like to unload them to someone who has a good knowledge about coins. He collected these coins while how was in WWIi. Here is a description of what I have: I have around 20 silver dimes that are so old, the dates have rubbed off. There is one dime dated 1907. I have one Morgan dollar-date 1917. I have several buffalo nickels. I have the following silver quarters: 1952' 1954, 1947, 1942, (2) 1943, 1956, 1941, 1946, 1944, 1942, 1954, 1963, 1961, 1957, 1950, 1944, 1960, 1924, 1907, 1951, 1964, 1936, 1955. I have several silver dimes, nickels, and quarters where the date has been rubbed off. I have not "clean" the coins or "polished." I would just like a "ballpark" amount of the coins I have....

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.

Https://www.instructables.com/id/Make-a-silver-ring-for-25-cents/ I am sorry to whomever posted this but this is illegal! And I think it should be removed! You can not do that to coins and should find a better way to make rings.. it is wrong. We are spending are tax dollars for these to be made.

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.

I live in Auckland, New Zealand. This in itself is awesome, but the only problem is that most Instructables like this or this call for American currency, and I seem to be running out of it. My options are to go to America again, or to find an NZ alternative. Obviously the latter is cheaper, so I was wondering which of our coins to use. Anyone?

I'd like to make a change sorter/counter that I can use with my PC to figure out how much money I have in some 5 gallon buckets of change that we gathered while cleaning some old fountains. (Yes, they said we could have what we found under all the gunk as long as we got the fountains clean and back to working order.) I want to be able to dump some coins in a sorter/counter and have my PC tell me how much there is in a given bucket of change. I don;t want to use estimating techniques like calculating the approximate number of coins of a given type by average known weight of the coins. I want an actual tally - a count - of all coins of each type and unknown coins (slugs). Any ideas?

I have a number of pennys that have all been mis-struck. One is a coin blank, two have been hit almost half off the coin, and one has the reverse of another coin pressed into it's obverse side. I know that the exact value can't be determined without seeing the actual coin but I was wondering if they could be worth anything more than a dollar or two.

Hey Guys, need your advise on this... Going straight ahead to the point, What can you suggest i can use for the movement of the Plate in the Coin Dispenser Design in the image? I need a component that does a push-pull action based on the design inspired from this video: http://www.youtube.com/watch?v=rwG-sG27360 Need your advise. :)

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.

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...

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!

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...

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?

Hey everyone! I need help with this certain project of mine. I bought this coin acceptor and turns out it can only accept a certain type of coin based on it's diameter. The problem is I need a multi-coin acceptor that can accept three types of coin which I will then hook up to a PLC. Tried looking for one over the net (Ebay and other sites) and I couldn't find anything. I also tried looking for some locally (I'm from a 3rd world country) and didn't find anything either. Any type of help will be useful. Thank you in advance!
Asked by deus.ex.machina 7 years ago
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?

Ok, Im have a little project about coin counter joined by LCD display and notify through audio system using arduino. Im using LDR sensor because it just a cheap project. Im not using a coin acceptor sensor as it difficult to be acquired. Is that any kind of program that is applicable to calculate coin instantly display coin total through LCD and can notify through audio system? or suggestion to use any other sensor? I hope anybody can help me.. thanks ^_^
