2009-D Doubled Die Reverse DDR-017

Description

Cataloged by VarietyVista as DDR-017 with die marker code UVC-3292 and die marker reverse DMR-019, this doubled die reverse variety was struck on a 2009-D Lincoln Bicentennial cent at the Denver Mint. The 2009 Lincoln Bicentennial program celebrated the 200th anniversary of Abraham Lincoln's birth with four reverse designs, and DDR-017 appears on the Birth and Early Childhood reverse (the first design), which depicts a log cabin in Kentucky where Lincoln was born. The cent was struck in copper-plated zinc weighing 2.5 grams with a 19 mm diameter and a plain edge. The primary doubling on DDR-017 manifests as a light spread toward the South, creating an extra log end on log number ten counted from the bottom of the cabin structure. The precision of identifying the affected log by its numerical position from the bottom demonstrates the detailed diagnostic vocabulary that VarietyVista applies to these varieties, providing collectors with exact reference points for confirmation. Three die stages have been documented. Stage A shows the reverse in early die state, with a light pre-die crack depression on the eyebrow and in the hair on the obverse, indicating early signs of die fatigue before actual cracking has occurred. Stage B represents mid die state, unconfirmed. Stage C is late die state, also unconfirmed. The pre-die crack depression noted in Stage A is a particularly interesting diagnostic, as these depressions represent the earliest stages of die failure where the metal begins to sink before fracturing into a visible crack. The log cabin reverse design, with its stacked horizontal logs providing numerous parallel reference lines, is well-suited for detecting southward hub spreads, and DDR-017's extra log end diagnostic demonstrates how even light doubling becomes identifiable on designs with repetitive structural elements.
