1787 Connecticut Copper. Miller 11.2-K, W-2875. Rarity-2. Mailed Bust Left—Partial Obverse Brockage Strike—VG-10 (PCGS).137.0 grains. A superb, very visually arresting error coin that at first blush looks like a wildly deformed double strike, which is what Robert considered it. In actuality, it is a partial brockage strike, a struck coin having flipped over and got caught about 70% off-center between the reverse die and an unstruck planchet, leaving the incuse, reverse impression of the top of obverse effigy’s head and the *CO of the obverse legends on part of the reverse. The great thickness of two planchets coming between the dies caused the planchet to spread wildly and even crack from the pressure. The non brockage strike also appears to be broadstruck, perhaps also caused by the extra planchet that was between the dies. Surfaces are dark olive brown, the coin retaining positive visual appeal despite uniform granularity. One of the neatest looking error coins among the richness of errors in Robert’s collection.From the Robert M. Martin Collection. Purchased from Mike Ringo in 1994.
