I was hoping not to lead the ID, but I thought it looked a lot like this one: http://www.forumancientcoins.com/gallery/displayimage.php?album=2232&pos=39
Unger, 566?
The type was struck in 1479-1485 (per Pohl) or 1482-1490 (per Huszár & Unger), with an average fineness of approximately .500 silver, and an average weight of .59023 g. This privy mark was struck in Nagybánya (now Baia Mare, Romania) as a collective bourgeoisie issue (per Pohl).
Did ou see the PM I did send you?
