This is a puzzle-can. It is a coin bank that is purposely shaped like a soda can, complete with fake pull-tab on the top. The coins go in the slot in the top, & there's likely a cap on the bottom to unscrew to get them out. The exterior of the can is a sliding puzzle. Using the single open space (seen at bottom) you re-arrange the sliding squares until it forms the proper picture.
There are American puzzle cans too, but this one is rather special. It may be 1 of the only actual merchandise to feature Mighty the Armadillo & Ray the Flying Squirrel. (Archie comics got a hold of them leter) Ray only appeared in the Sonic trackball arcade game (which was scarce to begin with) He appeared there for the first time, along with Mighty. Mighty appeared again in Knuckles Chaotix but remained somewhat obscure ever after. This can is a great piece to collect!
