You may still find the odd slot machine that pays you out your winnings in coins; however most land based casinos across the USA now operate on a ticket out type basis and as such by pressing the collect button or cash out button you will be issued by the machines with a printed ticket. You are then going to be able to turn that ticket into cash by visiting any of the ticket redemption machines located around the casinos gaming floor or you can visit the cashier’s cage to redeem those tickets, of you could opt to put the ticket into another machine and use the value of that ticket to play with!
