I pulled out a group of coins that i have been soaking in distilled water for about a month to clean today and about half of them seem to have developed this greenish hue. I had received a couple of coins this colour in my uncleaned lots but when ever I did the scratching test with a tooth pick, it seemed way to hard for bronze disease.
Today when I tested one coin the green covering came off pretty easy. It wasn't dusty like coming off but more scratched off. I do have some Gringotts BD killer whihch I am ready to use. Also if I do use the chemical, do I do the whole batch that was soaking together to stop one that shows no effects today from getting infected later.
I just want to guage everyones opionion that this is potentially bronze disease and I should go through with the killer, or am I looking at a soft patina. I havent had to deal with Bronze disease before, so learning as I go here.
Thanks

looks to me like :
- they are ready for a boil and a scrub - (healthy does of baking soda in water - 15 minutes)
- does not look like bronze disease
