How much is my 1907 $20 dollar mini St. Gaudens gold coin worth?

No scrathes or dents in really good condition

It is not an official US coin, it is a novelty item. You don’t mention size or composition of the coin. Assuming it is made of non-precious metal or at best gold plated with a very thin layer of gold; I would expect something around $10 to $20 dollars.

My best guess.
