1971 S Eisenhower dollar MS 66 ANACS 40% silver

Description

Fewer high grades the first year of this series.  Pricing triples for just one grade higher than this.  Right from the blue envelope to ANACS.  Also had them conserve it.  As these can build up some cloudiness.  Even in the mint package.
ANACS will not list "40% silver" on either the 71 S or 72 S.  They say it's because in those years all S mint marks Ikes were 40%.  I tell them, not every body knows that, it would be nice to see on the label.  73 S and 74 S they will list whether it was the correct weight to be silver.  As those years non silver S mm were released.  In mint and proof sets.
