1871 Shield Nickel Conservation Attempt

I've posted this one before but thought I'd create a new topic to post results of my attempt at conservation of this old soldier.

The coin was never going to get alot better but my goal was simply to arrest any further damage. I'm not experienced enough to tell for sure whether I was dealing with PVC damage or verdigris. So, I tried acetone first and the Verdi-Care product second.

It doesn't look like the acetone soak of a half hour or so had any real effect which I interpreted to mean that I was probably dealing with verdigis and not PVC damage.

The Verdi-Care which I was using for the first time following the instructions on their web site did seem to help but not completely. I did try some careful prodding with a toothpick. I didn't have any thorns available :-)

Anyway, I thought I'd post the results for others to make suggestions or comment.
