Since
America’s first stamps, new experimental issues have been created to
save money, prevent fraud, and more. These stamps are a lot of fun to
collect!
The USPS first tested self-adhesive stamps in 1974.
They became really popular in the 90s, so the USPS looked for ways to
produce them more efficiently. Before 1997, the stamps came on a
backing paper, or liner, that they adhered to. To cut costs, the USPS
experimented with linerless self-adhesive coils. On March 14, 1997,
these new stamps were issued to test the potentially money-saving idea.
