Agree, caused by some type of acid.

I would assume so also the question remains- would acid cause it to be so uniform in thickness around the whole perimeter? I would assume acid would eat away at it in varied degrees so that is why I find it a bit odd. Thanks for your input!

I'm thinking emersion in an acidic solution over a period of time. I've seen other copper coins in similar condition over the years. Even tried an experiment a couple+ decades ago which yielded very similar results.

So acid can reduce a coin thickness that much and there still be that detail? Just asking

One thing to remember is that acid will eat away the coin equally so that the devices and fields will remain constant. Check the search box under "acid coins" for other examples. We have seen a number of these lately. Edited by JimmyD

I used to make these type of coins all the time for my chemistry students to get a good object lesson on how nitric acid will dissolve metals. Copious amounts of dark brown gas given off and the solution turns a bright greenish color.

Alright! I have learned some new things today. I never would have known that acid could create such a perfectly thin wafer and still have that much detail on both sides. Cheers!

The give away on acid coins are the poor rough surface on the coin, the details have obviously been affected

 To the CCF If your coin is the same, then the answers will be the same. |

Are the pocks in the obverse likely from air bubbles being exposed?
