I also live in a State that allows Antique Slot Machines.
I called the Dept. of Gaming, several times, so I didn't get the same person.
They laughed at me & said, as long as you don't collect money or give away prizes or money we don't care about you.
We have our hands full keeping up with the Casino's.
Like Jason Said,
use common sense, don't allow anyone, Friends or Family to use Real Money.
Mine are all Ticket In & Ticket Out. No Cash is used. No Problems.
Good Luck with your new Toy & welcome to the Forum.
One won't be enough?
