I want to make a raspberry pi arcade cabinet but I don't know how you would have it to only allow the user to place their game of choice when they have paid, and to let them play more than once if they pay more than necessary

The requirements for identifying coins is a complex one, involving mechanics and elecro magnetics among others
Size of the coin (Thickness and diameter)
weight of the coin
Magnetic properties of the coin (Dont forget the double metal 1pound in the UK or the toonee in Canada) are complicated as is general shape
so before you can even get to the software there are a lot of hardware / mechanical issues to deal with
I would suggest getting an old vending or game machine coin slot and adapting that (Assuming it has a readable protocol or is purely mechanical with contact outputs denoting the identified coin) but this will limit your acceptable coins
you could go modern and issue an RFID tag to players where they can "Charge up" the tag and play within it. but this will require a link to the "Cash Register" so to speak
google "Coint Tester" for more info if needed
