Some of the Smurfs get turned into gold coins by Gargamel which get stolen by thieves.

In "Smurfette Unmade," when Scrupple said to Gargamel that he could not turn Smurfette back to her "evil" original self, his left hand shows four fingers. He should have five fingers in his hand. See more
Smurfette, stop sniffling.
But poor Sassette... Oh I have been so selfish... I'll never forgive myself...!
