From the detail that remains I can see a crown and a shield below and what seems to be some of the date above the crown. In the sunlight I can see the 3 things in the shield and the letters DOV behind the bust. I cleaned it rubbing it with my fingers only. Found behind an old house about 3 inches deep. Too bad its in poor condition, but the search was fun. Gotta go back when the weeds die out. Jabbo
