Would This Make Sense?

If you mean it has coins in it already that would depend on how long the coins have been in it. I had a friend a long time ago that had some old slot machines in his attic and he let me play a nickel machine but told me I could not keep anything if I won. So I put a nickel in and won three nickels,one Jefferson and two buffs.So if the machine you are thinking of buying is old then think of it as buying an old piggy bank.

I know of a guy who used to be a gambler, but not now. Just for fun, he bought himself an old poker machine, and now puts 'no cash value' metal gambling chips through it. It is a great party piece.

Actually a great idea. Although it depends on where you keep it, how you display it, is it legal in your area, for use in public places, etc.? For example someone I know has a small vending machine company. And much to my irritation, he has no interest in coins and runs through many, many of them daily. I used to know a person that owned a laundromat and collected so many coins he had a problem turning some in to the banks for what he was supposed to be doing.
If you just purchased a machine of any kind that requires coins, it would serve little purpose unless it is in a place where you could get a good turnover of coins.
