Good evening I put 5 photos coins with different liners. I would like your opinion. Thank you I studied about 350 coins of the dollar 1982 constitution. I have the Charlton Catalogue 67 edition 2013. My question concerns the 1982 Doubled Die because the catalog photo is very difficult to see for this lining.  Coin#1     Coin#2   Coin#3  Coin#4  Coin#5  |

Castor, it looks like machine or Strike Doubling for the pictures you have posted. The legends and date and jewels look shaved or smaller as a result of the strike with irregular steps. Don't think you have the Obv.-002 Double Die (Normal Jewels). |

It looks to me like Mechanical Doubling, but Charlton or someone may have just given it the name of "doubled die". Nothing is really doubled .. the planchet moves during striking (actually just on the way up, not down). |

The Charlton Catalogue used the term incorrectly (probably terminology carried over from the 60th edition Charlton?). I was a contributor to this section, but a lot stuff from the 60th edition was kept intact. The main argument I went after at the time, was to remove the 1968 DHL #2 from the catalogue... it was a matter of picking my battles. That said, Obv-002, as shown in both the 60th and 67th edition catalogues (note they used the same photo in both editions) is, in fact, Die Deterioration Doubling. To the best of my knowledge, a doubled die obverse for 1982 Constitution dollar, in the purest definition of that term (hub or punch doubled), does not exist. The coins in this thread are not doubled dies. In the 1982 Constitution dollars (I have probably examined close to 10,000 coins), I see Die Deterioration Doubling, Machine Doubling and sometimes a combination of both. Great photos, by the way - here is what I see: Coin #1 - Machine DoublingPhoto #1-1 - Machine Doubling, with early Die Deterioration Doubling seen at the top of 'N' in CANADA. Coin #2 - Die Deterioration DoublingCoin #3 - Die Deterioration DoublingCoin #4 - Machine DoublingCoin #5 - Machine Doubling (a great example, showing a nice offset and step-like doubling) "Discovery follows discovery, each both raising and answering questions, each ending a long search, and each providing the new instruments for a new search." -- J.

Hello SPP Ottawa Thanks for having to clarify that there was an error in Charlton and that the coin "Doubled Die" does not exist. You are the reference recognized by the numismatic community for your studies on the nickel parts (1968-1987) and this clarification coming from you will be beneficial for the numismatists. For the benefit of the French speaking numismatists who do not understand English I will translate into French your comment which you will be able to see on this link. http://www.numicanada.com/forum/vie...1403#p201403Thanks again. Here the French translation which I will put. Le catalogue Charlton a employe le terme inexactement (probablement terminologie reportee de la soixantième edition Charlton ?). J'ai ete un contribuant à cette section, mais beaucoup de la substance de la soixantième edition a ete maintenue intacte. L'argument principal pourquoi je suis alle à ce moment, etait de faire enlever le DHL 1968 #2 du catalogue. que c'etait une question de selectionner mes batailles. Ceci dit, Obv-002, suivant les indications d'edition des soixantième et soixante-septième catalogues (note ils ont employe la même photo dans les deux editions) est, en fait, un coin deteriore doublure. Au meilleur de ma connaissance, un coin double pour le dollar 1982 constitution, dans la definition la plus pure de ce terme (hub ou poinçon double), n'existe pas. Les pièces de monnaie dans ce message ne sont pas des coins doubles. Pour les dollars 1982 constitution (j'ai probablement examine de près de 10.000 pièces de monnaie), je vois pour des coins deteriores doublure, des doublages mecanique et parfois une combinaison de chacun des deux. |

This thread is a perfect reference as to how valuable this site is. I am about to look through a few hundred of these and, looking at the Charlton I'm thinking, "The photo is small, but that sure looks like Machine Doubling." Thanks! |

Maybe CCF could be promoted in the RCNA "Numisnotes"....

With SPP's help, the information was updated in June's edition of NumisNotes.
