The lowest-mintage circulation strikes are some of the Philadelphia issues, including those from 1948 (3,006,814), 1953 (2,796,820), and 1955 (2,876,381). Even in uncirculated condition, these relatively scarce pieces are available for a price. The real rarities in the Franklin half dollar series are those which show full horizontal lines across the depiction of the Liberty Bell on the coin?s reverse. These are known as Full Bell Lines, or FBL Franklin half dollars.
All FBL Franklin half dollars are scarce with certain dates unequivocally considered rare in the mid Mint State levels ? particularly MS65 or better. The most challenging of all FBL Franklin half dollars is the 1953-S, which is a five-figure coin MS64-65 range or higher.
