I'm hoping someone will be able to help me with the current 25 Kurus coins of Turkey. There is not much research on them here and the lop left one is a normal struck example - I put that for lookers to compare. The other three has various degrees of difference in apperance.
And on obverses one can see two different sharpness of busts and lettering around. Weak strike? Hub or die doubling? Anyone can help?
