The Mint reported a mintage of 4,000 for the 1827 Capped Bust Quarter, but this amount appears to be incorrect. No examples struck for circulation have ever been found, and only around ten proof examples are current known to exist.
Since the rarity of this issue was realized early on, restrikes were created from the dies still on hand at the Mint. The restikes can be found on planchets of copper or silver, and even overstruck on an 1806 quarter dollar.
The originals and restrikes can be identified by the style of the numeral “2” on the reverse of the denomination. Originals have a curl base 2 since they were struck using a reverse die of 1828. The restrikes have a square base 2, as they were struck with a reverse die of 1819. All examples, whether originals or restrikes, are struck from an overdated die with remnants of a “3” visible underneath the last digit of the date.
Restrikes of the 1827 Capped Bust Quarter come to auction periodically and command high prices. One of the finest known restrikes graded PR66 by NGC sold for $69,000 in July 2009. The ten known original strikes rarely come to market and when they do, represent a true once in a lifetime opportunity.
