This e-exhibit is based on a physical exhibit I mounted for the 2003 ANA Early Spring Show held in Charlotte, North Carolina. The exhibit was presented in four showcases. The first a basic introduction highlighted by a $25 bag of NC quarters spilling out that I had spiked with a few raw duplicates from the collection. The second case was dedicated to planchet errors and included an explanation of the planchet manufacturing process. The third featured errors created by failure of the dies and utilized photo enlargements in addition to the coins. The fourth and last case was reserved for errors created during the striking process. The explanatory text was supported by a simplified three-dimensional model of a coin striking press a machinist friend helped me craft. This became the highlight of the exhibit. The exhibit won “Best of Show” at the Charlotte ANA. It was later shown at the 2003 Raleigh Coin Club Show where it won Peoples Choice. It then traveled to the 2003 Summer ANA Show in Baltimore, Maryland where it won both its class and the Pobjoy Award for the best exhibit of circulating commemoratives. Its last competitive showing was at the 2003 North Carolina Numismatic Association Convention in Hickory, North Carolina where it again placed first. It has been shown non-competitively on several other occasions through out the state. Since Numismatists who specialize in collecting error coinage by type classify their collections using the PDS system, I chose the same method to divide both the physical as well as this e-exhibit into logical and manageable parts. However, in this case PDS does not stand for the three primary U.S. Mints operating today but for the three main areas were errors can occur - the planchet, the die and the striking process. PLANCHET ERRORS - Errors that occur due to the failure of some aspect of the planchet manufacturing process are covered in this area. Unstruck or blank planchets also fall into this category. more DIE ERRORS - Although much more frequent in earlier Mint history, errors made during the sinking of the dies are covered by this category. Also covered and the bulk of what makes up this category today are errors created by failures of the dies during use. more STRIKING ERRORS - Errors that occur due to the failure of some aspect of the actual striking process are included here. more |
