Another way of finding a list of the Great Americans series. Go to the PNC3 website, http://pnc3.org
. You do not have to be a member to access this.
Go to the reference section and choose "The Plate Number" Click on November 1995 ( the last issue ) and in the back of the journal is an advertisement by Steve Esrati. He was a Great Americans expert, and in the ad he lists all numbers and varieties ( up to that time? ).
