I'm looking at mine right now, I found them a few months ago. Man, half of them are dumb. One Just has some weird looking guy in a turtle neck sweater who is stareing at me. seems like half of them have a ying yang symbol on them. the slammers though were getting out of hand, I have ones that are a half inch thick. I think there were these special pog playing boards you could get but not to many people had them. It seems like pogs came out of nowhere around '93 they were just everywhere all the sudden and then by '96 everyone forgot about them.
My slammer was a 1/4 inch POS, but it was holofoil silver with a black skull in the center. I thought it was the shit. Would be a pretty nice memento to have, but I don't know what happened to them.
I pretty sure I have the slammer you are talking about it its got the shiny foil like paint job and a skull on it, but then again all pogs had skulls, ying yang signs or the 8 balls on them.
