Just catching up on old threads here,thought I'd put my two cents in. Everyone brought up good points, the ring is definitely poorly made, and has had a hard life. There are a lot of what look like cast marks to me, but Mike brought up a valid point about die flaws/weak dies/defects during stamping. My father collected coins for many years, and die flaws happen more frequently than you may think. But I agree with Gaspare, the REAL trouble is that hallmark. It is Austrian, indicating 800 silver content and Klagenfurt make. It was put in use in the early twenties, and it is stamped in. Sure looks legit to me when compared to other examples. So either someone has the original hallmark or made a copy of one...or it was period made. Imho, that is a bit of an oddball stamp to use or copy, although it could be done. I would like to examine it better under a loupe, but personally I would take a chance if it wasn't a lot of money.
