HI
This is an
Ottoman AR 30 or 15 Zolta coin minted under Ahmed III in Qstantaniyye (Istanbul) the date is 1115AH (1703AD).
Denomintion depends on the
weight:
30 Zolta - 15,04g 25,76mm
20 Zolta - 12,33g 13,64mm
15 Zolta - 7,21g 10,47mm
However, from the scan this coin looks
fake, but one cannot tell this without having the coin in hand. The reason I am saying this is because Ahmed III coin are high in silver content. This one looks like
Billon. But may be because of the image itself.
Best wishes,
