I have a 1986 proof set it the penny has some lamination issue I think I’m not real sure. Is real noticeable on by the obverse and reverse. Please let me know what you think

from the supplied pictures it looks like the penny was toned. Please look up there term "delamination" at erro-ref.com



The first pic makes it look like there is a white spot on the rim close to the L in LIBERTY which, in that picture, makes it look like zinc rot may have started and is coming up through the copper.

This is corroded from moisture so the penny is damaged.

Take out as fast is possible the coins. The JFK start to be contaminate also. This set was keep in the sun (UV) light, differential temperatures and those years the material inside are corrosive for coins. Hope an restoration (correctly and not by a TPG restoration) can brink your penny and halve back. will be very costly. Good Luck.

This will not spread and there’s nothing that can be done about the cent, it’s common but toast at this point.

I agree with DANIEL. In my Lab I do 'it for my self (really cost approx. 3000$). For moment it is OK at 90% after 3 years in the vacuum slab. I just experimented. 100 % no worth to be done for coins under 10K. Just buy a good shape new set.

OH Paul, you do not believe the restoration of an artifact cost so much? I will not deny your believes.

When I say is cost so much it is because is cost this if you really remade at the initial state. In general took 3 days of testing and analyzes. Why?, because this it is molecular science, and you has to remade the material at the initial state. Is not only deep and wash. Example: An cooper coins who is Cu, Zn and tin, who now has Verdi's. What mean this: the H and O from the molecules migrate to the surface and react with different externals agents made to produce this oxide which always will drain more C, H and O form the original material. Doing this will slows modify ionic structure. So in short this it is what mean to restore and artifact. I can wrote pages and pages for and how the approach must be done. Anyways, the study was already publish on Academia and you can consult (around 120 pages). Please just think about the ESD-DSX test cost, or the cost of the molecular composition not to talk about the surface salt, oxide, etc. All this work is not done by an unqualify employee.

After my early retainment from Health Care I opened this Artifact restoration lab. Just the tools costed more then 300K and all collaborators are at least Dr.

Paul, any time we can speak cordially , friendly and constructive about this. If you want, for me will be a pleasure. Your experience and knowledge can help as on our activity.
