Bluish Paper

In 1909, the Bureau of Engraving and Printing tried out an experimental stamp paper with some rag content (ordinary stamp paper was 100 percent pulp). Some stamps were printed on the paper and issued as a test; other values were only printed in quantities of a few hundred stamps.

The paper was very faintly bluish—some have called it a very light blue-gray. Most of the bluish-paper stamps are very rare.

4c orange brown Washington single

This 4c and the 8¢ singles on bluish paper are extremely rare, as are some blocks of the higher face values. The 1¢ and 2¢ denominations were regularly issued and are not as scarce.

2c carmine Lincoln Centenary of Birth single

This 2¢ Lincoln memorial stamp of 1909 was also printed on bluish paper.
