1945s - ms-64 1909 - f-12
Pretty much what I expected. The heavy verdigris should not be removed or you'll find some deep pits under it. You might have a little more...

I suggest you read the book Coin Chemistry to understand the toning process. In brief, it is well-known and scientifically proven that hydrogen...
Why not may I ask? How could you not like a product that's able to save coins like these? .....and I have many more pictures from not only myself,...
The obverse carbon spot held it back IMO.
Glowing luster! EF-45 :devil: LOL
