I have had this one for a year or so and finally getting around to attributing it correctly. D/D southwest? You guys know this stuff better than I. Found in a bag of 600 mixed wheat and memorial at a local auction. Chuck
I noticed in the Red Book a 56-d is listed as "D above shadow D" is this the same one? Also what is rpm #1? Is it the major or first one in the series of over mint marks? These things kill my eye's to look at very long. It's better to take a pic and blow it up or I guess maybe purchase a good microscope. Thanks Chuck
The numbers I listed are from the book - The Cherrypicker's Guide. That is how the coin is listed in that book. RPM #1 means it was the first RPM discovered for that date/mint by Fivaz & Stanton.
There are several organizations and individuals who maintain generally accepted catalogs on coin varieties. The coin pictured in this post The Cherrypickers' Guide 4th Edition Volume One (Fivaz and Stanton) - FS-021.1 CONECA (Combined Organization of Numismatic Error Collectors of America) - 1956-D RPM 1 NCADD (National Collectors Association of Die Doubling - John Wexler) - 1956-D WRPM-001 Charles Daughter (coppercoins.com) - 1956-D 1MM-001 Billy Crawford - 1956-D CRPM-1 Ken Potter - VCR1/RPM1 Walter Breen - ???? (I don't know) It should be noted that CONECA has cataloged this variety with UVC (549 and 550) and DMR (7 and 8). UVC stands for Universal Variety Code and DMR stands for Die Marriage Registry. Which indicates that there are 2 different known reverses to this variety. It should also be noted that although this variety carries the reference number (1) in all the above listed catalogs that doesn’t hold true for all varieties.
Intresting. I have been meaning to pick up the cherrypickers guide but have not. Guess I should. I find an oddity or rpm and it usually sits in my error box untill I find time to sort. Untill I can get the books I need I will be sending in a few more errors and rpm's over the next couple of days. Yes I know about coppercoins .com, I still have a hard time looking up the right rpm. Thanks for the list of information Chuck
