This specimen was lot 31159 in Heritage sale 3073 (Chicago, April 2019), where it sold for $3,120. The catalog description^[1] noted, "George III Counterstamped 1/4 Dollar ND (1797-1799) VF25 NGC, KM-Unl., S-Unl. Oval counterstamp XF Strong. Struck on a 1786 Mexico 2 Reales. Extremely rare and potentially unique, unlisted in Spink and with no recent auction comparables. The late 18th century emergency coinage is well-known as oval and octagonal countermarks on Spanish colonial 8 and 4 Reales, but no other 2 Reales specimens have come to light rendering the present piece of the highest rarity and the key piece to complete the 'set'! The host coin itself is toned a gunmetal gray with a darker peripheral ring, whilst the countermark field has filled with a gorgeous red-and-gold tone which immediately draws the eye. A vital piece missing from all major British collections, sure to be hotly contested thus."
