In the video, Lange discusses the options that NGC offers to collectors for variety attribution, which he calls "the ultimate in desirability." He explores examples of US coin varieties and how variety attribution is beneficial to both submitters and online viewers.

Lange has written 10 books about numismatics and was honored by the American Numismatic Association with its Lifetime Achievement Award in 2009 and as the Numismatist of the Year in 2017. The Numismatic Literary Guild honored Lange in 2018 with its prestigious Clemy Award.
