Mid-year Design Modifications:

Date Position

The first Susan B. Anthony dollars were struck in 1979 at all three mint facilities (San Francisco, Denver and Philadelphia).

The obverse die design was modified with a “wider” rim late in 1979. This design change affects P-mintmark dollars only.

The date placement on the die did NOT change, only the design of the rim. This “wider rim” design modification only gives the appearance of the date having been re-located. In fact, all of the outer design features near the rim appear closer including the stars, LIBERTY, and IGWT, but the date is the most commonly mentioned aspect of this ‘wide rim’ modification.
