The rare coin market so far in 2026 has been somewhat volatile, with greater price swings happening over a shorter period of time when compared to historical norms.
Dougan, Hatter, N.Y. 10-Cent Encased Postage Stamps
Greensheet & Friedberg® Price Guide
The Greysheet Catalog (GSID) of the 10-Cent Encased Postage Stamps series of Encased Postage in the U.S. Currency contains 1 distinct entries with CPG® values between $5,400.00 and $7,200.00.
Postage stamps encased in a brassy-metal housing were invented by A.M. Gault in 1861 to alleviate a severe shortage of coinage. They were issued only in 1861 by a handful of private businesses. A piece of mica (clear plastic) was used to protect the stamp in its frame. A small number of these fascinating paper money-token crossover items survive today and very few in top quality condition. This is a collectible worthy of greater attention as values have not been well defined for items of superior condition.
