1788 Connecticut Copper. Miller Obverse 14.2 Brockage. Rarity-8. Draped Bust Left. VF Details—Environmental Damage (PCGS).136.8 grains. Uniformly granular with a few areas of raised corrosion spots. The obverse is quite sharp, and was probably an EF or better coin when it became corroded. The brockage side is about 15% off-center, indicating the brockage maker was partially ejected from the dies before getting caught between the reverse die and this coin’s planchet. There is a roughly crescent shaped weak area flanking the 10 o’clock position of the obverse, as there was not enough pressure to fully bring up the die struck side due to the off-centering of the brockage side. A fascinating error coin and one of the small number of 1788 Connecticut Copper brockages that have survived to this day.From the Robert M. Martin Collection. Ex Coin Galleries Sale of July 2011, lot 530.
