I recently bought a silvered AE1 Galerius follis from an auction and realized it has several powdery light grayish-green patches on it that I could remove with a wooden toothpick. There were no pits or holes underneath the patches after they were removed. You can see the patches best above the second 'M' in MAXIMIANVS, above the 'E' in GENIO, and on the Genius' abs in the pre-cleaning picture below. There were several harder dark green specks on the coin's reverse and the Genius' right arm that I am less worried about. From this picture do y'all believe that any of these spots are likely to be bronze disease?
