Tora cota Mayan cheap rare Antique

Product Name: Tora cota Mayan cheap rare Antique
It looks like the univers is on the surface of it when the light is on it.. It should be at a museum or a castle. If I didn't need money I would definitely keep it. I don't know it's true value, please someone let me know of any antique expert to tell me more of this precious item. When I knock on it it sounds like copper mix with iron and other precious metal. cheap The colors change depending on the lighting or the sun or the dark. It can last for ever, I imagine the Mayan or the Roman empire using an item like this. Buy it for collection or to have a great display. The uPscale vintage by Rj&Rbj.
