Good Example is the AC Playboy chips
Before the big find, a $100 was worth over $1,000. But with the find, prices fell dramatically. So was the case with the $1.00 La Rue chips. There is probably a lot more examples....I say collect because you enjoy collecting, not as an investment, be it coins, stamps, cards or chips. Sure, there are rarities in all areas, but as we've seen as recently as the 25 cent Westerners, they maybe a ton out there, just noone knows it. Have fun.
