Small Sculpture/Figurine Florence "Missing Leg" Pieta A Giannetti

Hello. I recently purchased a small item for $1.50 at a thrift store. It's by A Giannetti who may or may not have actually existed. I've seen items by him sell for $15-60 or perhaps even more. I have also seen several of the same items being sold. I've seen a good deal of Mose, Pieta, and David, and some sculptures with horses...

I have yet to see anyone selling a Florence "Missing Leg" Pieta by A Giannetti and therefore I have no idea how to price it. Is it rare? I don't think one has ever been sold online. At least, not that I've been able to find.

Any light you can shed is be greatly appreciated.

Good
