Sulphide marble with lion Animal Figurine

1800’s sulphide marble - was well used - a long history of great grandparent and great uncles play This decorative sphere contains a small lion figurine inside. I’m shocked to see the prices for these sold on EBay Parkside Drive south of Bloor and keele station area My price is firm - priced below any comparable listing for this being sold in the vintage/secondhand market
