Having looked through my collection I found a few coins with green spots that I think may be bronze disease. I'm not sure though. Could someone give me an opinion on it? I've never encountered bronze disease before, so help would be appreciated. https://imgur.com/a/8JDwRnt Also, the pictures were taken with the phone flashlight on to better show the green parts. It may also be that when the coins were cleaned, some patina was left over, but then again I need to be sure. I don't want the coins damaging the rest of my collection
If you can take a toothpick and scare away at it, more than likely it is bronze disease. Please see Type 2 in the False Patina of the link below. https://www.metaldetectingworld.com/cleaning_coin_p3_patina.shtml
