A 1921 double eagle, graded MS63 by PCGS and pedigreed to the famous Norweb Collection, sold for an incredible $218,500 at Heritage Auction Galleries, yesterday (April 29).

As with many later dates in the Saint-Gaudens double eagle series, the historic 1921 was never released to circulation in significant numbers.

This makes it extremely scarce and valuable today, and a remarkable inclusion in Heritage's auction.

"The Norweb 1921 double eagle, is an incredible coin in its own right but greatly aided by its pedigree," said Todd Imhof, Executive Vice President of Heritage Auction Galleries.

Among numismatists, the Norweb 1921 double eagle is considered the most important coin in The Carter Family Collection, renowned for its broad range of numismatic rarities.

"In our most recent auction in Fort Worth, the glamorous Norweb pedigree helped propel a 1911-D quarter eagle to the top of the Prices Realised chart," said Mr Imhof.
