1788 Connecticut Copper. Miller 13-A.1, W-4535. Rarity-4+. Mailed Bust Left, CONNLC—Double Struck, Reverse Brockage—VF Details—Damage (PCGS).114.0 grains. Dies oriented at 270 degrees. A headscratcher of an error coin—the first strike was about 10% off-center, followed by a second strike that was die struck on the reverse but with an <em>another already struck coin</em> intervening between the obverse die and the already struck obverse of this coin, creating a brockage of the reverse on the already struck obverse! Thought the coin is somewhat wavy and the surfaces are a bit corroded, the incuse 1788 date is visible in front of effigy’s bust, and Liberty’s pole is diagonally through his hair and laurel wreath. The reverse shows two full dates side by side and very slightly overlapping, to great visual effect! We can’t imagine that many similar brockages exist, though we note the Miller 2-D also in this sale as a parallel double struck, brockage occurrence.From the Robert M. Martin Collection. Ex Coin Galleries Sale of August 20, 1986, lot 1392.
