It is advertised as such but there are many non-FBL halves sold as FBL but with the disclaimer "decide for yourself" which means "it's not really FBL."
Nope. Even if it was FBL it still looks AU, has hits all over it, and has that black gunk on it. This is not a coin to put in your collection unless you can get it for under melt.
If you have to ask consider NGC or PCGS graded Franklins. Lower MS grades tend to be much more affordable.
Here is the reverse of a lower graded example. MS 63. This is the Bugs Bunny FBL example. Even at the low grade one can clearly see the FBL's.
Means full bell lines on Franklin Half Dollars. It's one indication of how well struck the coin is and usually commands a premium by Franklin collectors.
One dirty little (not so) secret about bell lines on Franklins is that a lot also depends on the date/mm of the Franklin. If a Franklin has borderline FBL status for a date/mm where FBL is common, then the odds are that you'll get the FBL. OTOH, if it's a tougher date/mm for FBL then the odds are that you won't get the FBL.
