When I was rough sorting I noticed this 1956 D in the 1940's pile and thought the "D" looked strange so I put it a side to look at it today. No need for die markers on this one. How far down in grading should I put it due to the unfortunate Chia pet on Lincolns chin?    Edited by sheldius

Very nice RPM @sheldius. Some people lower the grade (i.e. details grade) with a spot like that. I'd prefer to just call it Fine (or whatever), but then mention the green spot. Also, are you sure that it is stable?

Soak in pure acetone. I bet some of that gunk can be removed. Very nice RPM!

Acetone unlikely to help, Verdi-care might, but the area under the ED will remain discolored.

RPM-001. The RPM I found years ago.  |

Thanks Spence, SamCent, Coinfrog, and Coop.
Hadn't heard of Verdi-care. Where do you get it?
I might have to fall back on my bronze disease treatments from museum artifacts - remove growth, solution of sodium carbonate to neutralize acid, distilled water to remove chlorides, acetone to remove water.
Not sure the coin would be same color after though.

I was challenged to come up with a contest for my 100th post.
So how about this - my favorite variety is this RPM. But it has bronze disease.
Contest-
Find a similar green coin, take before pictures. Use your best treatment on it. Take an after picture. Post them with directions.

Perhaps! Currently at a beach resort without any cleaning agents, so I'll have to wait a little bit.
I would create a post in the Contest section.

We have a contest section? LOL.  I'm very insular. I generally don't look outside Varieties and maybe CRHing. |

SilverCents - How well the corrosion is removed, with out damaging the rest of the coin.
