Some of them look nice Interest. Water staining on perth copper is very common.

Perth copper is notoriously bad for water staining. Some nice ones there!

nice coins
I have a friend who has a theory that the Perth mint washed the planchets through an acid wash (prior to the minting processes) which has resulted in the ccommon water stain appearance that we see across the later years
