<p>[QUOTE="Gavin Richardson, post: 2797998, member: 83956"]I do not think the two coins on the right have bronze disease. As [USER=42634]@chrsmat71[/USER] said, bronze disease tends to be powdery and can be easily scraped off. It's a matter of texture. If you scrape the two coins to the right with your fingernail and the green stuff is hard, it's just verdigris or part of the patina. No harm. The only spot that concerns me is the small spot in the middle of the far left coin. That spot has the coloration of bronze disease, but again, texture is your giveaway. And finally, it bears stressing that diagnosing anything from photos is far inferior to examining the coin in hand.[/QUOTE]</p><p><br /></p>
