1986D-1DER-001WS Trail Die Reverse

Description

Found by Chuck Daughtrey of Florida, this trail die reverse on the 1986-D Lincoln Memorial cent exhibits moderate fluting line extension into the stylobate beneath column #10, along with light step deviation under columns 6, 7, and 8, at an offset direction of 170 degrees. Trail dies — sometimes called shelf dies — occur when a die develops raised ridges on its working surface due to metal flow under extreme coining pressures. Unlike hub doubling, which creates a secondary image from a misaligned hubbing event, trail die effects are progressive deterioration features that develop during the die's service life. The 170-degree offset describes the angular orientation of the deterioration. Stage B die markers at mid-die state document the obverse with no noted markers, while the reverse shows a small die gouge at the bottom of bay #1 and a small die dot on the upper right side of column #12. Struck at Denver on copper-plated zinc planchets (97.5% zinc, 2.5% copper) at 2.5 grams and 19mm.
