Hello everybody. I'm writting to you from Poland and i would like to receive some information about my coin. How you can see the date in my coin is changed from 1770 (?) to 1780. Is it frequent thing ?

I think, this is an original coin, minted in Prag, Wardein Ignaz Keller; Herinek 944 (EvS -IK). The coin from 1770, Herinek 934, was minted by Wardein Anton Stehr (EvS - AS)

So it could be coin from 1779 changed to 1780 ? Minted signs are the same for 1779 nad 1780 (Evs IK)

I think it is a coinage-spezification and no supplement change.
Look the example in acsearch!

Abverse in my coin is little bit diffterent. How you can see D.G.R inscription on my coin is on the right side, in your example D.G are on the right side but R is on the left side

Any ideas?
