Bronze disease?
« on: January 29, 2014, 01:41:47 PM »
I'm not sure if those turquoise areas are traces of bronze desease or simply patina.

Thanks

I don't think it is bronze disease. (edit- I looked at the bigger picture and it looks even less like BD)

BD is soft and powdery, you can try to scrape it with something like a needle to make sure...if it is BD, some will come off pretty easily.

I also would not wax it (as advised by someone at FORVM).

I have attached a photo of a coin that has bronze disease. As you can see, it looks like powdery blisters; while yours has a nice smooth appearance.
