This unique and spectacular Walking Liberty Half Dollar major mint error is among the rarest and most valuable U.S. mint errors known.

All off-metals in the Walking Liberty Half Dollar series are extremely rare. These include two known on foreign planchets (valued at $25K each), 5-7 known on Quarter planchets (valued at $40K each), one known on a silver dime planchet (valued at $100K) one known on a steel cent planchet (valued at $125K) and a double strike with the second strike approximately 50% off-center (valued at $40K).

Combining two major striking errors on the same coin that is in a series known for extremely rare and expensive mint errors is unbelievable.

This Walking Liberty Half was struck at the San Francisco Mint on a U.S. Silver Quarter planchet. It failed to eject, remaining in the collar and was struck again 50% off-center. Another blank was resting on the off-center portion on the obverse during the second off-center strike.

PCGS recently certified and authenticated this gem mint error MS 65. This mint error transcends the error hobby and belongs in a collection of the finest U.S. coins.
