How a Major Die Break Errors or a CUD can happens? Coins are made by minting machines that apply tremendous stamping pressure to pieces of metal, leaving artistic patterns in the finished coin. The piece of metal, or coin blank, is called a planchet, and the hardened patterns that stamp on the coin are called working dies. There are two dies in a minting press, one die for the Obverse, and one die for the Reverse of the coin. After hours and hours,days and days of coin striking, the dies sometimes break under the pressure. Mint workers usually replace the dies before they crack, but sometimes several coins are produced before the workers find and replace the dies. If the broken dies go unattended for long periods of time, the break grows worse and worse, leaving larger and larger malformations on the struck coins. A large lump of coin metal left by a major die break is called a CUD. Read more: dniewcollectors.blogspot/2013/11/the-brother-and-sister-of-major-die.html#ixzz2kXACGi1g
