#1) What KIND of doubling do you think you're seeing? Fat letters, doubled image?
#2) Where on the coin are you seeing this event, obverse, reverse, motto, Date, MM?
As of now, I see nothing indicative of a hub doubling class 6 or 1-4. The details are VLDS, meaning
, metal flow and movement outwards plus the stretching/enlargement of the devices.
Quote:The Classes of Hub Doubling defined.
Class 1: Rotated Hub Doubling: Doubling where a second hubbing has been moved CW or CCW. The 1955P and 1972P are classic examples.
Class 2: Distorted Hub Doubling: This affects the outer design elements, separation lines normally above but can be under letters. Hub design variation.
Class 3: Design Hub Doubling: Most commonly known as Overdates(OVD), as in the Large Date over Small Date 1970S.
Class 4: Offset Hub Doubling: Where one hubbing offsets another in any direction, this is the "doubled ear" variety of 1984P.
Class 5 Pivoted Hub Doubling: Design elements "pivot" around a specific point on the die. Such as 1995P, date is pivot & untouched, Motto/LIBERTY are doubled.
Class 6 Distended Hub Doubling: Here a Stretching of design elements, only Class not showing a definite separation line. This is caused by an improperly annealed (treated) die itself causing stamped impression to "stretch"
Class 7 Modified Hub Doubling: This comes from trying to correct an error by failing to grind all off before hubbing again. Best seen on 1963D-1DO-001, very few in
LMC's.
Class 8: Tilted Hub Doubling: The design is tilted, showing as extra "bars" next to devices such as above L in LIBERTY or next to letters IN.
Class 9: Shifted Hub Doubling: Came to describe errors in "single squeeze" minting such as "wavy steps". Thought to have come from the snapping "pop" that comes from the pressure applied which causes a slight shift. Remember, this has been debunked as not a true Doubled Die by most. (see
http://www.traildies.com)By thinking of the motion within each Class's title, may help you visualize what each Doubling may look like. Some of the best on-line reference sites:
http://www.coppercoins.com/advsearch.php http://www.errorvariety.com/index.html http://doubleddie.com/ All these have extensive listings and libraries of information for most any error coin question you may have. The following pictures are examples of each of these 8 recognized classes of Doubled Dies.
Just noticed the location mentioned... date:9 took a hit,
on size, EPU smashed or is a grease-filled strike. No Premium for these machining problems, not even "errors".
