If anyone has any doubles they'd be interested in trading or selling let me know. Besides slot cards I've been collecting different coupons and coupon books plus arcade cards and a few other things. I have some doubles that I can trade or sell if there is any interest. I don't currently have all of my doubles listed on Delcampe yet but hopefully sometime soon.
I also collect the entry tickets used by many of the casinos in Europe and I have some doubles of those available also.
