Vintage Mickey Mouse doll with Hanna-Barbera copyright

Brew reader Rod Cockle found this item in an antique store: a plastic Mickey Mouse figure with a Hanna Barbera copyright on the back.

The figure is actually a bowling pin from a 1970s Mickey Mouse bowling game. Is this like those misprint postage stamps or coins that are worth five times their value because of a printing error? I would’ve liked to put one of these in my Hanna Barbera Treasury book – it would have drove the lawyers crazy.
