1788 Connecticut Copper. Miller 4.1-K, W-4430. Rarity-4+. Mailed Bust Right--Flipover Double Struck--AU Details--Environmental Damage (PCGS).111.9 grains. One of the more incredible-looking Connecticut copper errors we have seen in recent years. A mind-boggling piece that one could call a "flipover double strike" to keep things simple, but in reality this coin was probably "struck" at least three or four times. It appears the coin was struck normally first, just a little off center, which represents the obverse and reverse designs that take up the majority of each side, but even that strike shows evidence of doubling on the effigy, something common for the variety. Then the coin flipped over and received a partial reverse brockage impression, probably twice, given the extent of the planchet spread. The coin is wildly misshapen as a result, and the obverse and reverse detail fused together in dramatic fashion on the "front" of the coin. Dark brown surfaces with some reddish scale and spots of verdigris. Very sharp detail showing very little if any actual wear.PCGS# 687252.From the Sydney F. Martin Collection.
