They were available for use on regular letter mail, as well as on airmail, which was still highly experimental. #C1-3), arranged in the order of their issue dates. Of the approximately 750,000 pieces sold, only 3,500-7,000 are believed to have survived.The first US Airmail stamps, or US definitive postage stamps issued for use on airmail letters, were issued in early 1918. Perhaps $50,000 or a little more in encased postage eventually was sold and circulated, not nearly enough by itself to solve the nation's small change crisis. At least thirty companies took advantage of the advertising possibilities with ads stamped on the brass backing. Still, encased postage proved very popular because it solved the major problems of stamp damage and the necessity of opening stamp envelopes to count the contents. Increased production of brass and copper-nickel coinage in 1863 also undermined Gault. The government issued fractional currency the next year. Gault's enterprise ended on August 21, 1862, when the government issued postage currency in 5-cent, 10-cent, 25-cent, and 50-cent denominations.

A heavier brass backing, suitable for advertising purposes, completed the piece. A thin, transparent piece of mica covered the stamp, and an outer metal frame held these items secure. Gault's plans called for the corners of a postage stamp to be wrapped around a cardboard circle. On August 12, 1862, John Gault received a patent for his 'Design for Encasing Government Stamps'-that is, a design for encasing stamps for use as currency.

The government authorized the monetizing of postage stamps by July 1862 and soon began printing stamp impressions on bank note paper. Envelopes stating the amount of stamps contained within and cards bearing stamps were sometimes used to keep the stamps from sticking and being destroyed, and printers sold advertisements on large numbers of these envelopes. A resourceful public then used postage stamps as currency for small obligations, a situation that forced shopkeepers to accept stamps as change. Mint soon coined copper-nickel cents almost exclusively, but demand exceeded supply. Coins consequently commanded a premium over paper money. Many millions of dollars in gold and silver coins and even copper-nickel cents disappeared from the market as a result of this hoarding. In early 1862, just months after the American Civil War erupted, people predicted the hard times and shortages looming ahead and began hoarding resources, coins included. 1c Franklin Ayer's Sarsaparilla encased postage
