Just damage.

A filled die coin will have normal weight. A coin with metal removed will be lighter than normal.

Kevin added this on another site to remain nameless "There is going to be a second auction of certified non die varieties such as my collection of buffalo nickels, and also a 1974-D silver Ike, one of my favorite coins. This is something new for Heritage, especially including the links for the books, they have been extremely helpful."

He might have done all he could with the equipment and references available. That reinforces the desirability of sending the coin to NGC. They have resources and experience that Witter Coin's staff do not. Let us all know how it turns out. (The "Star Wars like weapon" was probably a portable XRF (X-ray fluorescence) gun for measuring alloy composition without damaging the coin. Most look like an electric hand drill with a tiny TV screen.)

Lots of interesting varieties here and a great many coins that have been featured in Kevin's books. Hope the sale goes really well! I've put the link and reference to Morgan and Peace dollars on VAMworld.

"RD" is used for copper, bronze and brass. That's why the label is a mistake, and probably why it was re-holdered. Presumably the top "photo" is of the original slab.

In this instance, I don't want to guess from the photos. (I have a proof purchased long ago, but it's sitting in a bank box along with my supply of original Skippy Peanut Butter and a fifth of "Ole Pappy.")

Nice find....hope your eyes are OK. What do you plan to do with the nickels?

'Cause it's a mistake.

So, should all clad coins be precoated with ferrous sulfate? MM's explanation is satisfactory for the Kennedy half. We can speculate that if it were dug from common acidic soil, an initial corrosion rate of 0.005mm for the first year or two is reasonable, and approximately 0.002mm per year thereafter for 75-25 copper nickel clad alloy. Apply these rates to the thickness of half dollar cladding to get the number of years of burial necessary to sacrifice almost all the nickel. [See. "Copper Alloys in Seawater: Avoidance of Corrosion," R. Francis, CDA-Publication 225 - February 2016.] MM just does not have the chemical background to accurately explain his "... 'exchange of copper' or being 'covered in copper molecules' which sounds like a much vaulted 'molecular copper effervescences' process" he keeps mistakenly referring to.

Look for the variety on VAMworld. To be credited with a discovery you'll need to write a description and demonstrate to the VAM collectors that it is NOT a known variety. That means posting your write-up on their discussion thread and defending it while members offer comments and their own ideas. Here are PCGS' photos of both sides:

Please explain the chemistry of how this happens. What happened to nickel?

The name suggests that debris stuck to a die. Multiple coins were struck, each showing a different stage of deterioration in the debris.

Recycled pre-1942 cents were also used for their tin content.

I promised to post this --- someplace --- hope this is the correct spot. CIVILIAN PRODUCTION ADMINISTRATION Washington 25, D. C. November 20, 1946 ARMaupin November 25, 1946 Tin, Lead and Zinc Br. Room 4346, SSB Miss Nellie Taylor Ross Director of the Mint. Treasury Department Office of the Director of the Mint Washington 25, D. C. Dear Miss Ross: Reference is made to your letter dated November 12, 1946 and past telephone conversations, in respect to using tin in the United States 1-cent piece. In studying the statement of the law included in your letter, namely that the alloy of the 1-cent piece shall be 95 per centum of copper and 5 per centum of tin and zinc, would be interpreted to mean that only a trace of tin would be required to meet the law. You have indicated that we would be willing to allow up to 0.25% instead of 1% tin which apparently was once used. It seems to us from the knowledge we have of the 1-cent piece, that any such quantity of tin adds no value to the coin and in fact probably hinders production. It seems to me that under the present conditions, the law would be fully satisfied if the tin content was held at 0.01%, or even less. However, we have decided that 1,500 pounds of tin you have requested immediately available to be divided as you find fit. In view of the fact that tin is so short in supply, we respectfully request that you keep tin content less than 0.1% or rather at the lowest figure possible to be considered as a chemical content. We believe that 0.01% is considered a definite chemical content and that such quantity can be readily detected by chemical analysis. Pursuant to Paragraph (m) of Order M-43, you are permitted to use not more than 1,500 pounds of tin in the production of coinage ingots, provided that the tin is used only in smallest quantities to meet minimum requirements of law. This tin may be distributed to coinage institutions as you see fit. The provisions of Paragraph (9) of Order M-43 (as amended July 5, 1946) are waived to the extent required to obtain the relief as authorized above, provided that all other provisions of Order M-43 and all other applicable orders and regulations of the Civilian Production Administration are fully complied with. Very truly yours, Approved: J. Joseph Whelan Nov. 25, 1946

From your photos, those rolls are just about "half baked."

Uhmmmm...I shall meditate on that ... Ommmmmm. Ommmmmmm.Ommmmmmmmmm

Good. That can be a difficult area to copy when making fakes. Best to send it to NGC for in-hand evaluation. Good Luck!

Drag and drop the photos to a reply window. JPGs work well.

Learning has a beginning but never ends.

Send your coin to NGC for authentication. The photo suggests at value of about $10,000 if genuine.

Thank you for the kind remarks.

Skip "red-dit" and "Craps List" and similar junk sites. Populated by crooks and scammers.

Cannot tell from the photos. Also need weight, diameter,thickness, etc. There are a few very high quality counterfeits but they are seldom seen. Off-hand nothing jumps out. Here's an authentic 1847 from a Heritage auction.
