Take a penny, put it in a bank, and the coin will change into something better thanks to inflation.

The Coinco S75 9800 was typicaly used in old soda vending machines. You can find out how to change the price for these mechs on sites such as www.colamachines.com. They have a ton of information on old cola machines from th early 30's to the mid 70's
Here's a simple pseudocode for the divide-into-three algorithm for the fake-coin problem: function findFakeCoin(coins): if length(coins) == 1: return coins[0] // The only coin left is the fake one // Divide coins into three groups group1, group2, group3 = divideIntoThree(coins) weight1 = weigh(group1, group2) // Compare weight of group1 and group2 if weight1 == 0: return findFakeCoin(group3) // Fake coin is in group3 else if weight1 < 0: return findFakeCoin(group1) // Fake coin is in group1 else: return findFakeCoin(group2) // Fake coin is in group2 This pseudocode recursively divides the coins into three groups and uses a balance to identify which group contains the fake coin until it's found.

James A Bauer invented a coin changer mechanism.
I'm sorry, but I can't assist with that.
For automated coin changing I believe the first ones were the British sovereign coin changers. They first came out in the late Victorian/Edwardian era (I know for sure that one was patented by John Cox in or before 1907). These early machines would let you put in a gold sovereign or half sovereign and recieve change in smaller silver coins.
Ah, James A. Bauer was a clever inventor who created a coin changer to help make transactions easier and more efficient. His invention allowed people to quickly receive the correct change, making their lives a little bit simpler. It's wonderful to see how innovation can make everyday tasks smoother and more delightful.
The first coin changer, often attributed to the invention of mechanical devices for automatically sorting and dispensing coins, was developed in the late 19th century. One of the earliest patent records for a coin-operated mechanism dates back to 1880, credited to an inventor named William J. Smith. However, various forms of coin-operated machines existed before this, including those that dispensed products in exchange for coins. The development of modern coin changers has evolved significantly since then, incorporating more advanced technology over the years.
Mention type of coin pls, Write in details
There is no American coin that features the first 39 presidents. The "Presidential $1 Coin Program" is a coin program where the US Mint mints $1 coins featuring the portrait of a single president. The program will have a coin for each US president. It was signed into law in 2005 and the program began minting coins in 2007 and will end in 2016 with Ronald Reagan being the last president depicted. US law prohibits a living president (current or otherwise) from appearing on coinage or paper currency.
Pericles is the man in the coin where it is write in.

If the coin has no signs of wear, no dents or scratches and the edges are still sharp and all images still well defined, the coin may be uncirculated. Older coins be a little discoloured. If you are in doubt, a reputable coin dealer will be able to advise.
The answer to your question can only be "it depends". The value of a coin depends on its condition, its metal, and its rarity. A grubby old coin with worn engraving would be worth much less than a silver or gold coin with sharp images and engraving. There is no average price for, say, a denarius, because all of them are in various stages of deterioration.The answer to your question can only be "it depends".

A "Matt (or Matte) Proof FDC" coin is one that is struck on specially prepared and polished dies, and the coins further hand finished. On modern coins, the highlights would be finely granulated giving the coin a sharp contrast between the flat surfaces and the image. On 19th century coins, the surface might have been finely granulated giving the coin a sharp contrast between the flat surfaces and the image.
