These ones seem to be a mystery they're almost paper thin under 17mm and practically weigh nothing, other than the indistinct symbols It's hard to make out what these could be. Like always any help is appreciated- Jake
The first coin does not look Arabic, but it does look like a double flip over strike. In fact, I don't think the second is Arabic either, but I have no idea what it might be.
I think the first coin (the one with the pronounced double strike) is from the Ottoman empire. In the second picture the design looks like that swirly thingy seen on such coins. Tamgra? Tufra? Tamka? T-something? (apologies to my middle eastern friends) Sellers of these relatively modern coins don't bother to describe the coin's devices. Anyway, something akin to this Vcoins listing (I'm not saying it's this coin... just in the same vein). OTTOMAN AR BILLON PARA of MAHMUD II AH 1223/26 QOSTANTINIYYE 0.1 GR & 10 MM Edited: Tugra! It's called a tugra
