what VK said, but i don't think it's active BD from what i can tell.. could use a coat of Verdi-care at any rate.
scrape suspected spots with your finger nail, if greenish powdery stuff comes off....then you have BD. if not...all good.
I don't think carpeting can get bronze disease. Hopefully those three brown spots will lift right off. Seriously though... what chrsmat71 said. And here's a link to some free online photo editor so you can crop and lighten your pictures, although that's not going to help the out-of-focus problem: https://pixlr.com/editor/ https://www.gimp.org/
Wow—those are great free photo editing programs, TIF! I wish I'd known about them before I purchased Creative Suite for $$$$!
I do not think the two coins on the right have bronze disease. As @chrsmat71 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.
