Two Franklin Halves - 1948 & 1955

A bit hard to say because of the dark toning but I would grade these as AU-55 and AU-53.

Of the two, the 1955 has a lot more lustre. I didn't capture it very well in the pictures.

Honest, the 48 looks as if xf-45. Hair on Ben is worn and
smooth. Reverse bell lines are worn and showing signs of
circulation.

The 55 maybe a AU at best. I treasure Franklin Halve dollars and
set up collections for each of my 10 grand children. Any smoothness
on the hair of Ben on the Obverse show it to be in a Circulated or
About Uncirculated condition.

On the Reverse when the bell lines have any smoothness or
wear then this degrades the coin from ms/au to xf

For the best information I use the ANA grading standards.
