I think you will need to learn to search zeno.ru

Hi,

I always do my research first in zeno.ru for at least 2 days.

But sometimes I skip and miss entire chapters.

I can identify a coin from ottoman empire from 1500-1900 (the classics ones).

But as suppose it is the case for this coin it is struck before 1500 and if for me look like as a ottoman akce maybe it is not (weight is 0,7 grams and material it is silver or bullion).

If you have a idea please share.

Thanks
