I have attached 5 images of different coins I have. Please let me know if you think any of them are indeed suffering from Bronze Disease.

Sorry about that. I'm having a big issue with images that would normally upload and be under 300kb now being way over and not uploading, really annoying and confusing.

@twood, are the light green patches on this coin chalky or smooth and adherent?

They appear to be chalky. I had rinsed the coins off with soap and water and the green stuff on the coin we are talking about looked like chalk does when it gets wet, the color bled out a little bit. Do the little green patches on the second picture look like Bronze Disease as well?

Watch the coins. If you see a change over a couple of weeks or a couple of days, it's BD.

I would echo @ks's comment above, but add that these coins should be isolated from the rest of your collection and each other until you know for sure.

I would consider deposits to be chalky, if when I pick at them with a wooden toothpick, I'm able to remove little bits.

Thanks for the help. I will at least put those two in a distilled water container for a couple days. I'll buy the materials I need for the sodium sequicarbonate solution as well since I'll probably need it later for the worse off coins (there are several more that look exactly like coins 2 and 5
