Hello everyone I found this Persian coin but I couldn't find anything exact on the internet about it. It could be Persia Safavid Dynasty Shah Tahmasb II and this Safavid coin of course is very similar but on the back my coin it is written "ضرب" and its the place of mint but this picture and other pictures i found have something else like "لا اله الا الله محمد رسول الله و علی ولی الله" on the back. Can anyone help me ID this please? Thanks. (And sorry about my bad English!!) This is the link of that Safavid coin:http://munzeo.com/coin/persia-iran-safavid-shah-tahmasb-12160193
