1788 Connecticut Copper. Miller 2-D, W-4405. Rarity-1. Mailed Bust Right—Double Struck—EF-45 (PCGS).100.0 grains. First struck as a 50% off-center brockage strike, then rotated about 45 degrees and struck again but perfectly centered and without obscuring the initial off-center/brockage strike. Light olive brown and uniformly microgranular, with a small curved planchet clip below bust on second, centered strike. A very similar coin was offered in Stack’s sale of Perkins duplicates, but the obverse side was double struck and the off-center brockage was of the obverse, not the reverse. A fantastic error coin that will delight even the most advanced collector of Connecticuts!From the Robert M. Martin Collection. Purchased from Mike Ringo, September 1982. <p>
