Franklin FBLs

j_h_s

Based on PCGS standards (bottom set of lines only), here's how I see it:
1948D - Hammered strike but PMD to lines (see Red Circles)


1949 - Also PMD (glare prevents full assessment)


1949D - Looks FBL but photo doesn't include left edge of bell

1950 = PMD at red circle


1950D - Appears FBL

1951D - Fill in bell lines at red circles


1952D - glare and incomplete photo unable to assess

1957D - Borderline and unable to call due to glare.

Here's how I tend to evaluate FBL ... you have a tiny ball bearing that you place at one end of the bell line and slightly raise that end of the coin. With the exception of the bell crack, the ball bearing should roll from one end to the other without stopping or going out of the channel.

Hope that helps. NGC includes the upper set of bell lines in their assessment.

I'll have to wait till I get home ... it's a "Blocked Site" from work.
