2006 DDO-003

My Nephew Chris and I have recently found six 2006 1c DDO-003. We sent all six to Dr. Wiles for attributing. This is his findings.All 6 are indeed DDO-003. Two are stage A, EDS. 4 are stage B, EMDS. Can someone familiar with this double die elaborate on the doubling process. Thanks Neal

Hi Neal and Chris - I moved your post over to a new spot since it concerns a different subject, a doubled die.

The 2006-P Lincoln cent, DDO-003 is a very nice find and one that is sure to be one of the high end doubled dies in the future since not that many have been found.

What has happened with this die is that during the hubbing process (single squeeze hubbing), the die was out of position with the hub during the first portion of the hubbing. At a point in time, the pressure forced the die into the correct position causing a secondary image to be formed. This positional correction (between the hub and die) occurred well into the hubbing cycle and caused all the obverse design elements to be affected which makes it both unusual and also a very strong Class IV doubled die.

This type of doubled die is different than the old style of doubled die (multiple hubbing) which was created when a second hubbing caused the design replication (or doubled die).

Congratulations on some very nice finds.

2006 ddo-003

I found another 2006 DDO-003. MDS I am still interested in the skull die crack. I recently bought a box of 2007 pennies one fourth of them have a huge die crack on the skull. Many of the 2006 and a large number of the 2007 pennies I look at have skull die cracks. Does anyone have any thoughts on this ? I have some picture I don,t know how to post them just yet.

Die cracks in the skull of Lincoln have plagued this series almost from the start. This area is the deepest recessed of both Lincoln cent dies and that in itself may be a contributing factor. Die life, die hardness (proper annealing and tempering), the conversion of iron into steel and striking pressure;all of these other contingencies can also play a part in the formation of die cracks.

If you find a lot of a specific die crack, it can be interesting to build a set of that coin with the progression of that anomaly, starting at the least area affected and building up to the most area affected.
