Coin and Paper Money Collecting/Expert Profile

Ask A Question


I can answer questions regarding certain Eastern European medieval coins, especially coins issued in Wallachia / Walachei/ Transalpina / Tara Romaneasca, Moldavia / Moldawien / Moldau / Moldova, Transylvania / Siebenbürgen / Transilvania for which I can usually make rough estimates of value based on past public sales. Medieval coinage of Serbia, Bulgaria, Hungary is also a field of interest but I usually can provide only identification, not evaluation, because of insufficient bibliography. Questions about coins of the Ottoman Empire and of the Golden Horde might get answer if you allow double of the usual time of 2 days. I cannot answer questions about medieval coins of Western European states or any Russian coins except Sadagura issues (1771-1774), nor questions about ancient or modern coins. NOTE: I will need to see at least a decent picture or a scan of any specific coin you ask about (with both sides, obverse and reverse). Please do not ask what a coin is worth without sending clear images of it along with your question.

2017-01-07 Mystery coin:

Hello,  This is outside my expertise but I can give you an answer. It was certainly issued by the Russian Soviet Federative Socialist Republic, some time around 1990-1993, and it looks like a medal for

2016-11-14 Spanish & Eyptian Coin:

Hi again Sarah,  This one looks like a 4 reales Spanish coin dated 1731, presumably struck in silver. Again its surface looks rather porous, but this sometimes may indicate a very aggressive chemical cleaning

2015-11-20 Old rare coin. Neopolian II 1860 copper coin:

Hello,  Modern coins are not my field of interest but I can give you a general answer for this one. As much as I can read from the (unclear) photos, on obverse there's the head of the Italian monarch Victor

Hello,  Sorry I haven't got the notification about your question until today.   It looks to me like a (medieval not ancient) Islamic coin, with Arabic script (Mamluks or around that geographical area)
