ANA - Abraded Die Varieties are fascinating, collectible but all-too-often overlooked die errors. Learn why and how they happen and see examples of popular and not-so-well known examples to complete your collection. Focus will mainly be on Buffalo nickels, although other series will be discussed. Instructor: David Smock
I feel that calling abraided dies "varieties" is inaccurate. A "variety" coin seems most naturally defined as coins that can be associated to a specific die or set of dies. This is not possible with abraided dies, since the abrasion did not exist on the first coins struck by that die, and any similarly abraided die could "become" that "variety" later in its life. To me, die abrasion is a die event along with things like chips, cracks, clashes, cuds, and gouges. Varieties are intrinsic properties of the die like overdates, RPMs, doubled dies, mint mark styles, and design varieties. Things that will be properties of the die from the time it strikes its first coin until it strikes its last.
I refer to them as die events. A variety shows on the first coin to the last. (Unless it is polished off the die) A die event happens during the life of the die and sometimes lasts until the die is retired. No wonder the terms are miss understood.
