Coca Cola: MagiCans - Magic Summer '90 Enamel Pin (1990)

Ah yes, who remembers the magic summer of 1990? Well I don't, because I was born in 1991. But if you have to believe this pin, it was magical! Seems as though there was REAL MONEY inside the cans?? Were they just soaked in cola? Doesn't sound very magical to me. Measures approximately 2,5 cm from top to bottom. Condition: Great!
