I have analyzed a 4-petaled, holed Khmer coin similar to the one pictured on Numista and it is composed of lead and antimony instead of lead and tin as is noted on Numista. Is this difference something that others have found?
I have read that antimony is a common constituent in lead ore so it may be that the presence of antimony in this coin is to be expected.
Any thoughts?
