Newman Portal Adds Video Series on Doubled Die Quarters

There is a strong tradition in U.S. coin collecting of pursuing die varieties, and, if a single launch point were identified, it would have to be the Levick plate of1793 large cent varieties published in the April, 1869 issue of the American Journal of Numismatics. Capably sleuthed by Jim Neiswinter in recent years, this photographestablished the benchmark for advanced pursuit of U.S. coinage: examples of each obverse and reverse die, and examples of each die marriage.

This worked well enough for 18th and 19th century coinage, but in modern times the gross output of the U.S. Mint defies attempts to collect (or even identify) all of theproduction dies. Nevertheless, collectors will collect. Today's focus is on finding more subtle differences in dies that are normally reproduced with a high degree ofuniformity. These have been notably documented by Bill Fivaz and J. T. Stanton in the popular Cherrypicker's series, and in other sources. Kristen Naylor, who haspublished a related book, has contributed to Newman Portal a number of videos that describe doubled dies in the Washington quarter series.
