I was a thoroughly grown up person when POGs were a thing, but we had to learn about them at work for a promotion.
My employer produced a big thick plexiglas slammer with a foil logo on one side. I remember laying them out in a path leading from the door of a convention center exhibition hall to our booth, to lure people to us at opening time. I remember running into SF author / tech writer Jerry Pournelle at the show; he didn’t know what to make of the slammer I gave him, but his wife said she’d explain. Also gave some to Penn & Teller!
I have, in a box of miscellaneous crap, a shrink-wrapped set of Sega pogs. They have Sonic and various related characters on them. I should really get around to selling those.
