According to Johl (Volume 1, page 181), only 10,000 of this coil were issued. They were made especially for a New York firm to send out advertising samples, similar to the 3c Orangeburg coil. Only a few rolls were sold to the firm, and the remaining rolls were distributed to some of the larger post offices across the country. Dealers acquired several rolls, but as most collectors of the time did not collect coils many were used and destroyed.
