1918-20 BENJAMIN FRANKLIN $2.00 & $5.00 SCOTT #523-524, 547

  In 1918 the U.S. Post Office printed 2 Benjamin Franklin stamps, a $2.00 orange red and black, and a $5.00 deep green and black. In 1920 they reprinted the $2.00 stamp in carmine and black.
  Interesting fact--the 1918 $2.00 orange red and black was mistakenly printed those colors but the reprinted stamp in 1920 was printed with the intended colors of carmine and black. Collectors did not know that the #523 was an error until the #547 was later printed.
