Very interesting post and before I will find the final explanation of Cincinnati to the Congress I put you here two interesting facts:
Quote:Miss Eva B. Adams, Director of the Mint, Treasury Department, Washington, D.C .
Dear Miss Adams:
As a numismatist, I have been working on the 1942/41 dime, which you probably know about. I have been trying to discover exactly how this variety came about, and in conjunction with someone else, have arrived at the following theory, and would appreciate some information relating to it, if possible: Late in 1941, when the 1942 dies were being prepared, the date logotype for 1942 dimes was prepared. Desiring to be sure the logo was perfect before using it on the master die itself, mint officials decided to test it. A 1941 die, perhaps a used one, that was near at hand, was lightly ground down to obscure part of the 1941 date, but very Little was actually lost in such light grinding (there is evidence of light grinding on the coin itself.) This die was then sunk with the 1942 date logo —when the logo was found to be perfect, perhaps after one of two strikes were taken from the die, it was used on the master die. The die that was over dated (on purpose) was to be discarded, but it accidentally went into production, producing the well known 1942/41 dimes. That is our theory, and we would very much like to know if this could possibly have happened, to your knowledge. 1 know that this information is not usually given out by mint officials, but we are sincerely interested in finding the truth behind this perplexing coin, and we are hoping that you will be able to help us in some way. Thank you very much,
Frank S. Robinson.
Possible Detectable Differences in the Reissue of a Past Dated Coin
In order to prepare working dies for a coin, a master hub or positive steel punch is required. This master hub must be complete in every detail including the date. In order to establish the date, in raised numbers, it is necessary to engrave them in a master die and then prepare the hub from this die. It is virtually impossible to exactly duplicate the numbers or letters in a new master die to correspond with those in a previous die. An expert could detect the difference and any coins made from dies prepared by this second hub would incorporate these slight variations. For instance, we do not have any hub or die for the U.S.
Peace dollar with the date 1923. This date would have to be reengraved with the risks of detection mentioned above. This problem arose in 1960 on the U.S. 1 cent (i.e., small date and large date). The appearance of a coin reissued after a lapse of 10 or more years can also be noticeably different due to changes in manufacturing methods such as type of upset on blank, size of planchet, clearance in collar, etc. These mostly affect the border, making it consistently different in width and chamfer. The state of the art of coin collecting has advanced to the point where such minor differences would certainly be discovered and used to identify what would be considered collectors' items.

PS: Just an example of the Mint Reports. I will find and post the MM study from the Mint. I love this discussion because represent what this forum is about: Learning, teaching and share not evaluations or others.
