1766 1/2P William Pitt Halfpenny NGC MS63 Brown. Betts-519, Breen-251, W-8350, Rarity-3. Copper. From a historical standpoint, the Pitt farthings and halfpennies rank among the most important Colonial issues of early America. This issue commemorates the efforts of William Pitt to have the Stamp Act repealed. The current piece is remarkable on several levels. It is a technical mint error struck on a cracked planchet that is visible from the obverse border at 10:30 and the reverse border at 7:30, extending in toward the center of the flan. It is also an amazing Mint State specimen, one of the finest we have seen. Both sides have a lovely blend of tan and chocolate color with beautiful, original surfaces. Light clash marks are visible in the obverse and reverse fields. Census: 1 in 63 Brown, 2 finer (5/14). PCGS population is 3 in 63 Brown; 1 finer. The CU Price Guide is $12,000.
