​4- take the < pencil > tool on "Hardness", choose the size to erase the remnants and follow slowly the coin listel by small sections, making errors easier to cancel.

​CONGRATULATIONS I'm not happened to this perfection, I'm an amateur.
​ Can you we know your software and with what method?

Cita: "Jarcek"​I would suggest taking samples from Indian States and India - Ancient. As well as Ancient Rome. These are full of unpredictable forms.

Cita: "chomp-master"​Also adding one specific request for a Chinese Empire coin I just fused with a rejected duplicate request (old Numista copyright which could be deleted that way) : https://en.numista.com/catalogue/pieces20609.html
