I have seen these horses done with one of two bases...either a wood music-box base, or a brass rectangular base.
This one also came in black. The plaque on the front of the base says "American Carousel c. 1900", and the coin
says "Limited Edition" with a run number of 5000 total.
These pieces are retired, I'm pretty sure IGI isn't making any of them anymore.
I am not sure what this piece cost when new.
