How do I know if a stamp is a reprint?
Clues to Look For
Reprints were often produced later, sometimes with different printing methods or materials. Original issues may show a specific paper texture, watermark, or perforation count that reprints lack. Color shade can also differ, and that is one of the most common differences collectors check.
The gum on the back can be another clue. Older originals often have gum that shows age, while many later printings use different adhesive. Because these differences can be subtle, a single clue is rarely enough to decide.
- Paper thickness and texture
- Watermark present or missing
- Perforation count and size
- Color shade compared with catalog images
Confirm Before You Sell
Use a respected stamp catalog and compare your stamp side by side with clear images of the original issue. Note the issue year, denomination, and any printing variety listed. Photos taken in natural light help you spot shade differences.
For a stamp that may be valuable, ask a recognized expert or philatelic society for authentication. Expert review usually costs a fee, and it is worth it when the stamp could be worth a lot. Keep your findings written down.
Original printings are often listed by catalog number and sometimes by variety. Write down any catalog numbers you find on the back or in your album. That information makes it easier for a specialist to compare your stamp with the right issue quickly.
Common mistakes
- Relying only on a shade difference without checking paper and perforations.
- Paying a premium for a stamp based on a seller's word alone.
