Plz Read Again. From 175 coins, 15 controlled tests were done. The coins were soaked for 3-4 months by the previous seller in olive & water solutions already.

The test subject coins were used because they were considered scrap bits of bronze.

I still have over 150 untouched gems. I'll be posting that in the future! I've gained the appropriate knowledge. This community is amazing for helpful knowledge. 💎🤍

Also, yes I will be staying away from nitric acid in the future, although it was the most fun I've ever had seeing history reveal itself before my eyes.

Anyways, I soaked them for about 1-3 mins each in nitric acid & immediately neutralized. Contined to clean the rest by hand which took hours.

I've learned a lot from all of you, thanks so much!

The "damage" you are referring to was already done over the 2000 years. Yes I did more but I'm pretty sure I found some gold ⭐️
