80 1975 Witherspoon post cards (Dubuque)

The John Witherspoon stamped postcard was issued on November 10, 1975. The postcard was issued to honor John Witherspoon, a Founding Father of the United States. John Witherspoon was a Scottish-American Presbyterian minister, educator, farmer and the president of the College of New Jersey.
I have 80 of these postcards in perfect condition, featured with the 9-cent Witherspoon stamp.
A few months ago, someone on E-Bay was asking $1.00 for 3 of these post cards
If you'll appreciate them, you're welcome to have them for the trouble of picking them up.
