ComicMan Posted November 3, 2022 · Member Share Posted November 3, 2022 (edited) Near the ears and on the bottom left of the coin looks kinda worrying. Sorry for the terrible crop-jobs, I tried doing it on mobile and it does not look good I know.

ewomack Posted November 3, 2022 · Supporter Share Posted November 3, 2022 What I've heard from others more experienced than me on this forum - if it's crumbly (i.e., breaks apart when prodded with a toothpick) it could be BD. If it's solid it's likely malachite and fine. But I would wait for people more experienced in such things than me to chime in first. 3 Quote Link to comment Share on other sites More sharing options...
Kali Posted November 3, 2022 · Member Share Posted November 3, 2022 Top coin, it looks fine, just a hard deposit. The second coin, the photos are a bit blurry/bad to even tell. 1 Quote Link to comment Share on other sites More sharing options...

I will try again in the morning with some natural light. Thanks for reassuring about the first coin I was really worried about that one!

John Conduitt Posted November 3, 2022 · Supporter Share Posted November 3, 2022 (edited) They look ok. The green looks like it has been there a long time. If you cleaned them you might actually cause bd. The top one is billon, so might be less likely to get bd anyway. I don’t know what the bottom coin is (not Roman Imperial anyway) but it might not be bronze either.

Don’t worry about the Postumus ant, it’s not BD; it’s called intra auricular cerumen. 2 3 1 Quote Link to comment Share on other sites More sharing options...

Romismatist Posted November 4, 2022 · Member Share Posted November 4, 2022 I think that both are fine. The Postumus above is billon with more silver than bronze, so risk f bronze disease should be low. The deposit does look more like malachite. The Amisos AE is likely fine too. The deposits there don't look too bright green, which indicates verdigris rather than bronze disease. Just my $0.02. 3 1 Quote Link to comment Share on other sites More sharing options...

Octavius Posted November 4, 2022 · Supporter Share Posted November 4, 2022 Not bronze disease. Don't treat them; they're fine. 2 1 Quote Link to comment Share on other sites More sharing options...
