These coins are really cool looking but I dont know if they are real, fake, old, or whatever. If you know anything about these coins please let me know.
First coin on the left is a Persian fals, probably dating from the 17th or 18th centuries ? I'm not sure of the identity of the others, but they look like Mughal bronzes.
Strange black constrast upon them, and way a coppery shine, but thats your modification and analysis works i suspect. There is no reason to fake persian coins. Their values are rarely high but historically ofc priceless. They are in other terms interesting as echoes from the past, just not a modern capital. I posess a few myselfe, but only one real fine speciment of all those.
