I've got a nickel, I've got a dime...

But they're of no use to me. Apparently, a couple of years ago all the slot machines in Las Vegas were re-tooled so they only take bills or "Tickets." Apparently, this saves a lot of labor and allows the casinos to eliminate most of their cages and save money. Oddly, I've noticed there is a lot more "Penny" machines, where the minimum bet is just 1c. But you have to put in at least a dollar.
