3c Deep Violet, Orangeburg Coil (Scott 389). Deep rich color and sharp proof-like impression, neat strike of wavy-line machine cancel, two light creases FINE APPEARING EXAMPLE OF THE RARE 3-CENT ORANGEBURG COIL. The Orangeburg coil was made by the Post Office Department in 1911, specifically for use by the Bell Pharmaceutical Company. The 3c coil stamps were used to send samples of their products to physicians. Due to the quantity of mail, they were put through the first-class cancelling machine at Orangeburg, New York. The Orangeburg coil stamps’ use on third-class mail, and the fact that philatelists were generally unaware of their production accounts for their rarity. Many have small faults such as corner creases or small tears. Ex Maffeo. With 1987 P.F. and 2007 P.S.E. certificates

2c Carmine, Coil (386). Mint N.H. guide line pair, wide balanced margins, beautiful bright color and sharp impression EXTREMELY FINE. A SCARCE MINT NEVER-HINGED GUIDE LINE PAIR OF THE 2-CENT VERTICAL COIL, SCOTT 386. According to Johl (Vol. 1, p. 111), the Bureau switched to Perf 8-1/2 for their coils after a very short period of time. The Perf 12 coils proved to be too susceptible to falling apart in the machines used to affix (and make) the coils. Scott 386 was one of the first to be discontinued and therefore is very scarce in Mint N.H. condition. We have offered only approximately a dozen since 2000. Ex Morris. With 1992 P.F. certificate

6c Red Orange, Bluish (362). Mint N.H., vibrant color as fresh as the day it was printed on deeply blued paper, perfectly centered with wide and balanced margins EXTREMELY FINE GEM. THIS PHENOMENAL MINT NEVER-HINGED STAMP HAS BEEN GRADED SUPERB 98 BY P.S.E. — THIS IS THE HIGHEST GRADE AWARDED TO DATE AND THE ONLY EXAMPLE TO ACHIEVE THIS DIFFICULT GRADE. THIS IS WITHOUT QUESTION THE FINEST EXAMPLE IN EXISTENCE. During the early stages of production of the 1908-09 Washington-Franklin stamps, the Bureau tried to solve the problem of paper shrinkage that caused off-center perforations and resulted in a large number of unusable sheets. Armstrong notes that up to twenty percent of sheets had to be discarded. The first such experiments resulted in the Bluish Paper stamps (Scott 357-366). Rag cloth was added to the wood pulp mixture, but this did not have the desired effect and the experiment was discontinued. With 2008 P.S.E. certificate (Superb 98, SMQ price $37,200.00). Apart from the 1c and 2c, this is the highest grade awarded to any Mint N.H. Bluish paper issue, and it is the only example to achieve this grade. The next-highest grade awarded to date is a 90.

10c Yellow, Coil (356). Mint N.H. pair, incredibly wide margins, essentially perfect centering, intense color EXTREMELY FINE GEM. A SUPERB MINT NEVER-HINGED PAIR OF THE 10-CENT HORIZONTAL COIL, SCOTT 356, WHICH HAS BEEN GRADED XF-SUPERB 95 BY P.S.E. THIS IS BY FAR THE HIGHEST GRADE AWARDED TO ANY MINT NEVER-HINGED EXAMPLE OF THIS COIL. According to Johl (Volume 1, page 181), only 10,000 of the 10c Washington coil stamp 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 large post offices across the country. Dealers acquired several rolls, but because most contemporary collectors did not collect coils, many were used and destroyed. Our computerized records encompass fourteen years of auctions. In that time we have offered in Mint N.H. condition only four singles, three guide line pairs (including the single and line pair offered in this sale) and three pairs. With 1996 P.F. and 2008 P.S.E. certificates (XF-Superb 95, SMQ price $35,000.00). This is the only Mint N.H. example of Scott 356 in any format to achieve the grade of XF-Superb 95. A Mint N.H. pair has been graded 80, and two pairs and one single in OGph condition have been graded 95.
