I've got this coin last month. It's a akce coin from Ottoman Empire akce, minted 1603 (1012 AH) by Ahmed I in Sidrekapsi mint. The coin is small, less than 20mm in diameter, and very thin (and light). Quality - vg perhaps. Can it be silver?
Can anyone give me more info about this coin? Catalogue reference? Value? Is grading correct?
Thanks in advance
