From Stamps of the World

In 1889, Seebeck developed a novel plan for the Hamilton Bank Note Co to print stamps for foreign countries. He offered to supply the stamps for free, provided that the stamps would be dated and invalidated at the end of each year, to be replaced by a new series; unsold (invalid) stamps would be returned to Seebeck for sale to collectors; Seebeck retained the right to reprint any invalid stamps as needed for sale to collectors. This process damaged the confidence of collectors in the so-called Seebeck issues of Ecuador, Honduras, Nicaragua and Salvador.
