Boy...I have looked at this coin a bunch of times now...hoping someone would answer! lol Before I offer any advice, I need some clarification. I cannot tell from the pic with is on the coin. At first glance it just looks like it is worn with a grainy texture, but after further looks...is it simply covered in dirt? What is the size and
weight?
If it is simply dirt, start with soaks and brushing and after the dirt is gone, we can
work on any encrustations that lie beneath.
