A minute alteration to a stamp design added to distinguish later printings from earlier printings by a different firm. Secret marks may positively distinguish genuine stamps from counterfeits.
The nickname for various Latin American issues produced 1890-99 in contract with Nicholas Frederick Seebeck, the agent for the Hamilton Bank Note Co. of New York. Seebeck agreed to provide new issues of stamps and stationery each year at no charge, in return for the right to sell remainders and reprints to collectors. The resulting furor destroyed Seebeck and blackened the philatelic reputations of the countries involved.

Removal of stamps from envelope paper. Most stamps may be safely soaked in water. Fugitive inks, however, will run in water, and chalky-surfaced papers will lose their designs entirely, so some knowledge of stamps is a necessity. Colored envelope paper should be soaked separately.

Special stamps
Regular postage stamp issues that fall outside the traditional definitions of commemorative and definitive stamps. In the United States, holiday issues such as Contemporary Christmas, Traditional Christmas, Hanukkah and the like are considered special stamps. They are printed in substantially greater quantities than commemorative stamps, and sometimes return to press for additional printings. Love stamps are also considered special stamps.
"Stamp or stationery item distributed to Universal Postal Union members for identification purposes and to the philatelic press and trade for publicity purposes. Specimens are overprinted or punched with the word ""SPECIMEN'' or its equivalent, or are overprinted or punched in a way to make them different from the issued stamps. Specimens of scarce stamps tend to be less valuable than the actual stamps. Specimens of relatively common stamps are more valuable."
Speculative issue
