Hi everyone, I posted about a John Quincy Adams dollar that had an obverse mat finish and a brilliant shiny reverse. I questioned if it may be a missing clad layer. The consensus from the experts here was that is was PMD. However, I soon found that I had 2 others with the same issue. I asked about the unlikely possibility that all 3 had PMD that was the same. That question was unanswered, so I decided to post it here. I'm pretty puzzled and hoping someone can help me understand how 3 Presidential dollars from different years can have the same 2 different coloured side issues? Thanks so much!       |

Jess1234 have you got George Washington. here is some thing to check for if you do . what you are looking at is where the statue finger comes around the object . she is holding, here is the images the metal between the fingers is raised when it should be pressed in the tripled finger looks like punching as you can see the pressure is outward when it should be the opposite. let me know what you think   |

all you got to do is read Wexler theory on proximity markers. this is all in his writings.

@Rocky: What the heck does your posting have to do with Jess1234's question, other than to spam the heck out of it.
@Jess1234:
You pose a great question, I hope that someone will be by shortly to help you with that answer. I might come tomorrow though due to the holiday.

Jess1234, As to the color. I think it is due to environmental toning. The way they were stored, maybe in a collectors' folder. One side was exposed to the air and the other side was not? John1  Edited by John1

@Jess1234:
john1 poses a great answer here, and your images seem to reinforce it. Notice how the side that show the presidents profile are the one that is more matte and the liberty side is shiny. If I were to place these coin into a folder like a Whitman cardboard folder, I would have the presidents showing as opposed to the common device of the Statue of Liberty.

John's explanation certainly makes sense and would explain this! Thanks so much for that John1! And thanks Dearborn for keeping a close eye on this! I really appreciate it! And for Rocky, I have many Washingtons. I will definitely look into Wexler's for Lady Liberty's torch holding fingers. I didn't even know it was a thing. What a great community! Thanks to all!!!! And here's something from me to you, just for fun! Found it online and thought it was so cute and VERY TRUE!!!  Edited by Jess1234

Hi again Rocky,
I've gone through Wexler's website and can't seem to find this variety. Can you please send me the link where you found the Lady Liberty fingers error on the George Washington dollar?
Thanks!

Jess Wexler done a study on various die states . one item he point out is proximity markers. if you use them you can not go wrong. I studied him read alot of his writing . ok Jess in the Washington dollars there is 3 types . they are being certified A B C at PCGS . I dont know what they are yet. I am going to try an find out. you have great one keep up the good work.

There are missing clad layers on these. NGC has certified a James Monroe $1 Coin missing clad layer. Presidential dollars are composed of the same three-part clad layers as the Sacagawea dollars. Planchets missing an outer layer show one side in rich copper color, as the pure copper center of the coin is exposed. This bright red is a sharp contrast to the "golden" appearance on the other side of the coin, adding to the drama of this error. Because coins missing a clad layer are thinner than normal planchets, they show weakness in the design especially along the edge of the coin. The image and some other Presidential dollar errors are discussed further in the link. https://www.ngccoin.com/news/articl...ollar-Coins/ and https://www.ngccoin.com/news/articl...Dollar-Coin/Otherwise Ive not seen enough examples to know about how the finishes look over time and with environmental exposure other than what Ive read, such as the sacagawea that uses the same same three-part clad layers https://www.PCGS.com/news/color-of-...deeper-tones |

Those coins as also the Canadians Dollard has the same things. Everything is due to storage. I put them in Slabs, In capsules and 2x2 and same thing. Where I keep the coins is permanent 16 deg. and low humidity at 25. Now light except when I go to look for something, now mushrooms or others contaminants. The air filter machine it is a military standard one. After a time the coins show like missing the coat on. Become matte and took the color of manganese. I have no idea why. Also certified coins by all majors TPG become same. Only one coin rest same in my own slab which was the test for vacuum the slabs. No scientific answer yet. |
