This page is designed for the new anomaly type called Design
Extension Dimples. While we are unsure of the exact cause of this phenomena, both Mike Diamond and I feel that it is
hubbing related. Rather than affix a category (error or variety) to this oddity, we are simple calling it a die anomaly.
The discovery piece is credited to Fred Weinberg and has been encapsulated by ICG. Mike Diamond has also written an article
concerning Design Extension Dimples in his column "Collecotrs' Clearinghouse" in Coin World.
If more of this anomaly type are found, which I am sure will happen, a designation
will be applied to each individual find. Weinberg's find will now have the designation of 2011D-100DEDO-001AJ.
The attributes for this anomaly type can be seen as depressions on the coins
surface that extend from the peripheral design elements in an inward, radial pattern. Refer to the pictures below of 2011D-100-DEDO-001AJ.
2011D-100DEDO-001AJ
The above pictures show the dimpling on the coins surface (raised on
the die) extending from the affected design elements. The pattern is inward and radial in direction.
The black arrow points to another dimple from just to the inside of
the first lock of hair. The white arrow point to a die wall dent on the fore head line of Andrew Johnson. This is almost positive
proof that this anomaly was created during hubbing and not created by the strike .

Design dimples are seen under the letters of E PLURIBUS UNUM onthe
2008D Lincoln cent. The obverse of this coin does not have dimples.

2010P-5DEDR-001
The obverse of this 2010P Jefferson nickle does not show the anomaly
called dimples.
The reverse, however, does show particularly strong dimples on all
the perpherial letting and even the word Monticello. This is the first strong dimple die to be found from the Philadelphia
mint.
Note: This coin was found by
Tanaka Davis.
