Hey jfee, I bought a few Proof sets awhile back and opened up a 1961 set that had the quarter and nickel loose within its sealed bag holder. The plastic with in the bag holder that separates the individual coins had somehow got compromised over the years. The toning is only seen through light refraction and has a MS red shine when looked at from above in other lighting environments. Which makes me think its through a natural process and not chemically induced. The nickel had a nice subtle light blue toning as well, and its not the first time I've seen toning on coins from the chemicals used in the old vanilla envelopes
packaging, but it is a little rare for it to be so evenly and heavily toned in my opinion regarding proof sets. Luckily the coins hadn't got scratched by each other because an older gentleman had collected the set and never moved it around when in his possession.

Images provided are TrueView images of a 2022 D. Lincoln shield. With the newer technology being introduced throughout the years, I am wondering if the Okuma LT2000 EX horizontal lathe with its twin spindles and four-axis operations which was introduced in 2012 replaced the older model cnc that only was able to do 3 axis's for the dies created another type of doubling with the 4 axis cnc capabilities. Look at the B in Liberty, it has a doubling like look and it just makes me wonder if the designs and wording on the newer coins coming out our purposely Beveled with a smooth transitioning upward/downward edge that barely makes lettering look fatter and creates a Mirage like reflection for any type of light intensity or angle that blends in compared to the doubling that occurs before 2012. Obviously the Mint doesn't like making mistakes because it makes them look bad, so what if they designed it to make it even harder for doubling to be seen if the alignment is a little off, but it's just a theory I have been wondering since I've been looking into some of there new practices. A few other places the same mirage like look can be seen in a few other places. Hopefully the images are high quality.
Cheers

| If you weight them, then get a scale that does two 0's after the decimal, example(5.67 grams). Or make a basic scale with two coins and put both coins on the same piece of wood and balance them. If you can't balance them at the same position then one is obviously heavy than the other, obviously scale is better though. Just a quick comparison option. |

| Toning is a natural process and certain chemicals can speed up the oxidation process, but doing that is considered a damaging the coin or devaluing the coin. If it was a super rainy month and a very humid environment it can start the process faster, as well a wrong metal alloy composition, the combining of planchets or the metal cooled down too fast or slow.Heat is a big factor in toning. Toning can happens on one side for a while then it will eventually reach the other side depending on the metal compositions. When you say if the mint is responsible for it, it will either not get caught and leave the mint, and the mint won't know if a toning issue happened because of them so they wouldn't do anything If they catch it at the mint they will melt it back down and try again. If your coin is missing a clad layer? Does the edge of the reverse meet the obverse (Washington side) is it rugged? Or smooth? I see the close up of the reverse side edge has rugged like particles where it's supposed to be sharp and smooth. Does it look like the finish have shiny at all? Is it rusty or, does it look like a piece of metal with a white haze? |
