2005PR-25DER-001T Trail Die Reverse

Description

Documented by the Trail Dies catalog with pictures and information courtesy of Ken Potter, the 2005PR-25DER-001T is a trail die reverse variety found on a 2005-S Proof Minnesota State Quarter. Trail lines extend from the tops of all the trees on the reverse, with the offset direction measured at approximately 010 degrees — a near-northward displacement that creates faint secondary impressions of the tree canopy shifted slightly above their primary positions. The commentary notes that this die will be more noted for its doubled die characteristics than for the trail die effect, suggesting the same working die that produced the trail lines also exhibits hub doubling, potentially making it a dual-variety die with two distinct types of die anomalies coexisting on the same piece. Die marker information is listed as unavailable, limiting the die-stage documentation for this variety compared to entries with full marker inventories. The Minnesota State Quarter, part of the 50 State Quarters Program (1999-2008), depicts a lakeside scene with a fisherman, a loon on the water, and a forest treeline — the trees whose canopy provides the substrate for the trail die effect. As a proof issue struck at the San Francisco Mint, this coin was produced on specially prepared planchets using polished dies, yielding mirror-like fields that make even subtle trail die impressions more visible against the reflective surface. The clad proof composition weighs 5.67 grams at 24.3 mm diameter. The 010-degree offset measurement demonstrates the precision with which trail die displacement vectors can be characterized, helping researchers understand the mechanical conditions during the die contact event that created the secondary impressions.
