And you advise to clean coin with VerdiCare? I am little bit afraid of cleaning this coin. Because it is against the first rule of numismatic - don't clean your coins.
verdicare is not abrasive. its a safe and effective as a surface debris remover. it conserves the coin and does not strip them clean of luster or original patina. the verdigris on this coin may spread over time and that's why it was recommended.
I cant comment on value or slabbing
