I used to love those things. I've got a tin with hundreds (if not thousands) of pogs in it around somewhere (and a slammer that flashes and makes noises when you use it).
When the premiership pogs first came out I got a Man-U shiny in my first pack (that I got free with The Beano, IIRC). I swapped it with someone for a Gameboy cart.
Had a big tub of the Star Wars pogs, but I'm not sure what happened to that.

Probably got lost during a move.
I must've been ~12 or so when I was into pogs. Damn, can't believe it was ~13 years ago that I was playing pogs at middle school.
