I think stated odds are actually where I get uncomfortable. There were always accidentally rare cards, purely from the luck of how packs were filled, and what was rare in one region was probably the common one in another from random chance in distribution. A lot of the card sets had a way to send off 5p or so for the last couple you missed, to fill the album at the end of the year. Somewhere that morphed into artificial scarcity, and kids everywhere being set up to buy five sets worth of cards, to maybe get a full set.
