What’s a Cud Error?

A cud error occurs when a broken die strikes a coin. The broken die disrupts the design transfer process, leaving a raised impression on the planchet where the die was broken.  Additionally, cud errors can vary in size and location, and the severity of the error affects the value of the coin.

Valuable Cuds on Coins

The Colorado cud error quarter is typically found on the reverse near the majestic mountain range depicted in the design of the coin, as shown in this article. 

Furthermore, cud errors only form along the ridge around the edge of the rim of the coin and block entire devices. For instance, check out a 1989 Cent missing the letters “God” of In God We Trust.

Grading and Value

While Colorado cud error quarters are not exceptionally scarce yet, their value depends on several factors. Additionally, depending on the severity of the error and the coin’s condition, a Colorado cud error quarter can range from a few dollars to hundreds of dollars.  The key considerations include:

  • Severity of the cud error: A more prominent and well-defined cud error generally commands a higher price.
  • Overall condition of the coin: A coin in better condition (uncirculated or lightly circulated) is typically worth the most.
  • Grading by a reputable service: Professional grading services like ANACS or NGC authenticate the coin and assign a grade based on its condition. A higher grade (indicating better preservation) can significantly increase the value.
