A really cool, large piece which is a little bigger than a silver dollar. This is a very popular design going back to at least the 16th century and can be found on all sorts of medallions as well as a few types of coins. The hallmarks on this one identify it as .800 silver and made in Vienna, Austria sometime between 1925 and 1975. It's also marked by the manufacturer "SCH. R", but I have not been able to determine who this is.
here is 1 on Ebay that has a good description of what is on the coin. link: http://www.ebay.com/itm/19th-Centur...337?pt=LH_DefaultDomain_0&hash=item1e88f54179
By the way, an extra dot on the "ship side" would have been helpful. It's "In Tempestate" (in the storm). The original Georgstaler, from Mansfeld, just had St. George and the dragon, and the CoA on the other side. Since they became popular (as good luck charms), other mints made similar pieces. I think it was Kremnica where the other side was first added ... Christian
