1948-1963 FRANKLIN MINT STATE HALVES

90% FULL BELL LINES = 90FL or 90FBL

On the reverse of the Franklin Half Dollar, the Liberty Bell on the reverse consists of two sets of bell lines; an upper set of three lines and a lower set of two. For a coin to be designated 90FBL it must exhibit 90% bell lines with interruptions at the bottom two lines of the bell no more than 10%. Whether a coin exhibits this depends on the striking pressure the dies were set to when the coin was struck.
