Two-Tailed Mule Quarter

Coin World just recently reported the existence of a 3rd known example of the remarkable two-tailed Washington quarter mule. The coin has two reverses, and as such cannot be dated, but it is believed to date back to the 1960's.

Do you feel like you know the difference between a mint error and a "damaged" coin? Do you know the difference between an error and a variety? If not, you should take the ANA's correspondence courses ""The Modern Minting Process", and "U.S. Minting Errors & Varieties." They are excellent courses which will teach you all the fundamentals (and more) about errors and varieties. You will then have a solid foundation to grow and learn as an error or variety collector.

Here is a link to the ANA's correspondence courses:

The Denver Mint is very concerned about catching any errors before they make it out of the Mint, as this article details. Interestingly, the Mint employs a tool for catching rotated dies, and also for checking the coin's thickness. Additionally, the article shows photos of the Mint employee visually checking coins (which is done every 15 minutes.) The odds of a cud getting out are slim.

Here is a link to the Coin World article (be sure and view the photos in the article.)
