Laibstain. Lightly toned and nicely struck coin with good luster. We had an MS 63 coin for a long time in the set, not being able to find an example to fit the set for nearly a decade. Truly not very easy to find in MS 65 and better, but a few are available with some searching.
David Akers: The 1913-S Barber Half Dollar is very scarce in mint state and moderately rare in Gem condition. However, it is more available at this grade level than the other two Half Dollar issues of the year, the 1913 and 1913-D.
