1788 Connecticut Copper. Miller 7-K, W-4490. Rarity-6+. Mailed Bust Left--Double Struck--EF-45 (PCGS).
A thrilling piece for specialists, a wonderfully crude and dramatic error strike of a very rare variety in tantalizingly high technical grade. Double struck far off center where the reverse received a bold second impression of the die and the obverse shows a blank impression from another planchet. The planchet was heavily flawed to begin with, showing striations and a large void that was exacerbated by the second strike that occurred in the same area. This piece probably saw little if any actual circulation, which is understandable given its bizarre appearance. There is very little wear present, and the light brown surfaces have a slightly frosty character and there appear to be remnants of real mint red in the dentils of the second strike on the reverse. A handful of light scratches are seen on both sides. By far the sharpest known of this rare variety, and certainly the most interesting!
