So my girlfriend went into Detroit with her mom and came back with some Sonic cards from 1993 - There are 2 different sets - one has screenshots from different zones on the front and tips and bits of information on the back - the other also has random information on the back - but the front is actually a peel off sticker and they are pretty awesome and I have 2 sets of those ones. Anyone else ever see these at all? have them? or know if they are worth anything. I don't know how common these are.
