According to Mike Rother's article on Sheldon Brown's website, the Super Sport was made from 1964-1973. "Before 1965 serial numbers were stamped onto a rear dropout. Beginning in 1965 serial numbers were moved to the head tube and the following date system was used for all Schwinns except Paramounts. The letter at the beginning of the serial number indicates the month of manufacture, skipping the letter "I." For example, "A" = January, "B" = February, and "J" = September. The second letter of the serial number indicates the year of manufacture (not the model year), beginning with "A" = 1965. Skip the letter I & O. Sports Tourer KH017873, for example, was built in October 1972."

If the serial number is on the headtube, not on a dropout (thingy the rear axle goes into), the second character in the serial number must belong to this set: [A (year=1965) through H (year=1972) or J (year=1973)].
According to Bob Hufford's Schwinn Lightweight Data Bible, er, Book, the color Burgundy was offered only in 1971.
Thus, Rose, your bike is almost certainly a 1971. See The Book entry here:

In 1971, this bike cost $136.95. In 2007 dollars, that's $694.39.
