This is a vintage, late 20th century, limited edition cast polyresin or ceramic, head of a wolf or coyote that was distributed by Mill Creek Studios and designed by Joe Slockbower. This was not hand carved nor is the medium stone. These were molded and produced in a multiple of 4000 copies. The estimate is based on actual recent past recorded auction sales of comparables. Retail 'asking prices' can be higher and vary.
