Dug this ring yesterday at a site in Savannah, GA that dates back to the 19th century. So there is literally everything there from colonial/rev war to civil war to modern trash at this site. I believe that this ring could be period (mid 19th century) or older and is silver. Not sure the composition of silver? All of the silver coming out of this site looks like brass or copper at first- has downtown crud all over and ugly. Anyway I can make out the hallmark but I am not familiar with jewelry hallmarks. Does anyone recognize this hallmark?
