1910 One Cent Edwards VII

There were no "painted" large cent coins. Without looking at what you think you are seeing, I have no idea what you are talking about. And the coins are bronze, not brass, regardless what you think the apparent color is. I think that you must have the lighting and magnification up way too high, like other coins that you have mentioned on here.

i will put up some photos later. I will show you what I am finding on these coins.

I have an enameled 1908 Encased Cent. I do not believe that it was done by or for the RCM.

here is a full image

here is what the wrap looks like around the letters. to put that on a coin would be very difficult.

It is not paint. It is just surface chemical reaction with something that has come in contact with the bronze at some time in its life. The "wrap-around" that you talk about on the letters is just more of the same thing, but concentrated into the nooks and crannies where normal handling or cleaning can't touch. Also, some of what you are seeing in the "wrap" is some Die Deterioration so that the numbers or letters aren't crisp and appear to be "melting" at the base. That's not paint or "build-up"; it's how a die that was well-worn was striking the coin. If you look at any Vicky, ED or George large cent that has seen circulation, you will see "gunk" that has collected there in those tight spots. Most collectors call it "Vicky gunk" and it is a mixture of human body oil, dirt, grit, and remnants of whatever was on the hands of anyone who handled it for 50-60 years. Just a person's sweat is alkali enough to change the color of bronze or silver. Just go through hundreds of posts on here to hear people talking about removing the gunk with toothpicks, hawthorn thorns, rose thorns or stiff toothbrushes. As far as the discolorations, now you see why large cent collectors have pondered about cleaning coins or not and what can be used to remove it.

If you are already into the third of Rob's books, you are reading too fast. Read slowly so you understand what's going on. I helped where I could with Rob on his first 3, along with a couple other fellow collectors from an older coin site. In the intros to the books, he mentions and thanked those who helped him and all of them check into the CCF site from time to time. Yes, he is a good writer and an even better historian. Some of the dark staining on the early cents will not come off with anything, since it's a chemical reaction and not a paint or coating. Take a few old worthless coins and start trying things to remove evrything.

I agree with @Coinfrog and @okiecoiner
