Sacagawea dollar-quarter mule error
This Sacagawea Dollar / Quarter mule error will be sold in Stack’s Bowers Galleries’ August 2012 Philadelphia ANA World’s Fair of Money Auction

This remarkable error was first discovered in 2000 by Frank Wallis of Mountain Home, Arkansas, and that discovery piece was subsequently sold by Bowers and Merena at the August 2000 ANA Millennium Sale for $29,900.

The sale of that coin spurred national interest in the "misstrike," as it was dubbed by the U.S. Mint, and by autumn of that year several other examples had come to light, by which time a total of three different die pairs were recognized and described by David J. Camire, author and first authenticator of the variety.

The example to be sold by Stack’s Bowers Galleries at the Official ANA Auction in August is attributed to Die Pair 1, and shows the characteristic die crack from the rim through the F in OF on the Sacagawea dollar side. The coin is a beautifully lustrous and brilliant Superb Gem, graded MS-67 by NGC, and displays lively rose and orange iridescence on both sides. Ranked  #1 in the popular 2010 reference 100 Greatest U.S. Error Coins by Nick Brown, David Camire and Fred Weinberg, this lovely mini-dollar / quarter mule represents an important opportunity to acquire a highly coveted and rarely offered U.S. Mint error. Indeed, opportunities such as this are few and far between in the error coin market.

The coin will be offered as part of our eagerly anticipated Rarities Night session, scheduled for Thursday, August 9, 2012, at the Pennsylvania Convention Center in Philadelphia. Complete catalogs for the Official August 2012 ANA World’s Fair of Money Auction are available by request by calling 800.458.4646, and online at

Perhaps “Rewarding Mistakes” would be a better title.


Are there any estimates of how many may have entered circulation? Correct me please if I’m off-base, but given that the dies were locked in and presses run at fairly high speed, a lot of coins must have been struck before anyone discovered the mismatch. Unless all of them went into the same hopper it could have been difficult to retrieve everything that was produced.
