I was going through the monthly mintage reports Roger Burdette put up on the Newman Numismatic Portal. I found a discrepancy with what I have listed for 1902 Liberty Nickels. I had 31,489,579. The reports Roger put up shows 31,480,579 for 1902. I knew I had pulled this info from the Red Book. In checking, I first looked at my 1965 copy of the Annual Report, and it also shows 31,480,579. I then went through the Red Books. I found the number changed in 1968 (it was correct in prior editions). So apparently, there was a typo changing a 0 to a 9 for the 1968 edition.Next up are some issues with the Buffalo Nickel numbers.
Years ago, while going through the 1965 Edition of the book "Domestic and Foreign Coins Manufactured by the Mints of the United States" I noticed a 19 coin discrepancy for the mintage of 1913 Buffalo nickels. This book lists a mintage of 60,852,239 while all of the references seem to have: 30,993,520 Type 1 29,858,700 Type 2 60,852,220 Total
