The best stamp collecting influencers covering US stamps, worldwide philately, first day covers, postal history, and philatelic investing. Find your next stamp collecting mentor.
Philately is the scholarly study of stamps and postal history — encompassing paper types, printing methods, perforations, watermarks, and postal routes. Stamp collecting is the broader hobby; philately is the more academic pursuit within it. Most advanced stamp collectors on CollectibleFind use both terms interchangeably, though serious philatelists focus on study alongside accumulation.
The most valuable US stamps include the 1918 24¢ Inverted Jenny (airmail error, $1M+), the 1867 1¢ Z Grill ($935,000 at auction), and the 1868 15¢ Lincoln E Grill. More accessible valuable stamps include the 1909 Lincoln 2¢ imperforate, the 1893 Columbian Exposition set, and the 1869 Pictorial series. Stamp creators on CollectibleFind cover key US stamp identification in dedicated tutorials.
A first day cover (FDC) is an envelope franked with a new stamp on its first day of issue, typically featuring a printed cachet design. FDCs are collected by cachet maker (Artcraft, Fleetwood), date, and topic. More affordable than mint stamps, they represent both philatelic and postal history interest. Stamp creators on CollectibleFind cover FDC collecting strategy and cachet maker identification.
Check the Scott Specialized Catalogue number by cross-referencing design, denomination, and color. Note the perforation gauge, paper type, and centering — all affect value. Unused stamps with original gum are worth more than used. Any stamp with a printing error should be expertized by the American Philatelic Society (APS expertizing service) before assigning significant value.
Essential: stamp tongs ($5–$15, never touch stamps with bare fingers), a 10x magnifier loupe, a perforation gauge, a starter album or stock book, and the Scott Simplified Catalogue for beginners. Hingeless mounts are preferred for mint stamps. Watermark detecting fluid identifies hidden watermarks on classic stamps. All are linked in the CollectibleFind Supplies section.
Mint stamps are unused with original gum (OG) intact — never hinged (NH) or lightly hinged (LH). Used stamps have postal cancellations. Mint NH stamps command the highest premiums. Cancelled-to-order (CTO) stamps — cancelled but never used for postage — are worth less than genuinely postally used examples. Understanding these distinctions is essential to buying at fair market value.

Stamp errors include inverted designs, missing colors, imperforate stamps, and double prints. The most accessible modern errors are imperforate pairs and missing colors on US commemoratives. Error stamps are extremely rare — found by carefully examining new issues immediately upon purchase. The APS expertizing service authenticates suspected errors. Several stamp collecting channels cover error identification and recent finds.
