Don;
What I collect are the back designs, not the front designs with the bar codes. The fronts follow designs by the slot vendor and what the casino wants to use for name, etc.in short lasting thermal print. While the backs are printing press printed with casino names, pictures, logos, etc. which will last as long as any printing press product.I have just under 300 backs in the draft catalog to date. I would estimate at least 500 backs exist to date.
