Silver101 Pillar of the Community Canada 1081 Posts	Posted 11/03/2020 8:28 pm I'm looking at a quite nice 1911 NFLD 50c on ebay (easy to find if you're interested. It has a "tiny spot of verdigris in the reverse legend" and it's graded MS-62 by ICCS. I would say the grade is accurate, might actually be MS-63. But I'm not sure how much verdigris detracts?

DBM Pillar of the Community Canada 9862 Posts	Posted 11/03/2020 10:34 pm That's not verdigris it's PVC gunk. Verdigris is found on copper and bronze. The damage is done, it needs to be removed from the holder and treated with acetone to prevent the damage from worsening. "Dipping" is not considered cleaning... -from PCGS website Edited by DBM 11/03/2020 10:40 pm Report this Post to the Staff
Silver101 Pillar of the Community Canada 1081 Posts	Posted 11/04/2020 05:18 am That was my concern - that coin is hose in that case, correct? Whatever the original grade was - and let's assume it's accurate - it's about to drop significantly. Report this Post to the Staff
sel_69l Bedrock of the Community Australia 21786 Posts	Posted 11/04/2020 05:31 am I think it is a silver oxide/sulfide stain on the rim over 'EOR'. Can be removed by a professional who knows what he is doing, but will leave some evidence of localized chemical cleaning anyway. Report this Post to the Staff
DBM Pillar of the Community Canada 9862 Posts	Posted 11/04/2020 09:57 am The grade won't drop. The value however should take a substantial hit. The assigned grade is not a price tag. "Dipping" is not considered cleaning... -from PCGS website Report this Post to the Staff
