ONE OF THE FEW USED OFF-COVER EXAMPLES OF THE 1959 5¢ ST. LAWRENCE SEAWAY WITH CENTER INVERTED.
There are about 200 mint Seaway Inverts in private hands. Quite a few of the Seaway Inverts were actually used by the public before they realized what they had. With only 16 examples recorded on cover, it would seem even a used example would be far rarer than mint however catalog values seem to indicate to the contrary.
