Die variety specialist/collector/author Brian Allen took on the enormous task of doing the attributions for the $1 doubled dies of all series, including the Ike dollars
. Brian noticed similarities among many of the listed obverse doubled dies for the 1971-S Ike dollars

for that date. His tireless research showed that many of the 1971-S doubled dies were actually the result of doubled master dies and/or doubled working hubs.
