It was not until early in 1908 that the Post Office Department issued some coil stamps of the 1902 series for use in vending and stamp affixing machines, but purely as an experiment. They were found to be satisfactory and as the Department realized that a demand existed for this type of stamp it was less than three weeks after the new design had been issued in the ordinary form that it was also available in coil form.

As in the previous issue they were made from the regular 400 subject sheets which were perforated twelve in the vertical spaces between the stamps and then cut into strips of twenty. The vertical guide line at the center of each strip of twenty, which were pasted together by hand and rolled into coils of 500 and 1,000. These were coiled on one half inch diameter pasteboard cores.

Splicing
The repair of a break in a roll of stamp paper, or the joining of two rolls of paper for continuous printing. Stamps printed over a splice are usually removed and destroyed before the normal stamps are issued. Not to be confused with the traditional paste up pair which will have straight sides to the stamps at the join, not perforated sides.
