1906-D $20 Liberty
Broadstruck (Out of the Collar)
NGC AU 58
UNIQUE
SOLD

This is the only known United States $20 Gold Piece that was broadstruck out of the collar. It expanded in size and has a plain edge. There are 5-7 known partial collar $20 gold pieces that have sold in the $5,000 to $15,000 range.

$20 Liberty gold pieces were only struck at the Denver Mint in 1906 and 1907. This is the only known broadstruck $20 Liberty gold piece from ANY U.S. Mint. It is possible that there was an issue properly setting up the dies and collar to correctly strike these gold coins since it was the first year of striking, creating this unique broadstruck mint error.

In 1905, the Denver Mint was testing the new presses and equipment and would only strike gold coins in 1906 and 1907. The press was setup to strike uniface bronze medals which were the diameter of $20 Liberty gold pieces. The design read DENVER 1905 on the obverse. These medals were struck as part of a ceremony celebrating the opening of the U.S. Mint in Denver.

Major Mint Errors on United State Gold Coins are extremely rare. Gold coins were examined and highly scrutinized before being put into U.S. Mint bags for circulation. It is exciting that this unique broadstruck $20 Liberty was accidentally struck and unintentionally released from Denver Mint.

Another world-class $20 Liberty major mint error is the unique 180 degree rotated double struck, which is available for $150,000. I previously sold a unique $20 Liberty struck 15% off-center that is currently valued at over $100,000.
