"bought" a set for six drinks at the bar. Well it was actually six drink chips traded for the set NIB.
That would be roughly $18 at the time. Bartenders discount made it free. The owner approved of the deal and she used the chips for years, for our friendly kitchen table game, before someone stole them.
Originally people got these for trading in Marlboro miles off the packs of cigarettes.
Nice for a home game, durable injection molded plastic.
