How it works
No catalog skills needed. If you can take a photo, you can identify a stamp.
Lay one stamp on a plain, light surface. Use daylight and fill most of the frame with the stamp.
You see the country, year, catalog number, condition notes and an estimated value range.
Each stamp is filed by country with its value. Add notes, compare similar stamps and export a list.

Value ranges combine catalog prices, recent auction results and market listings. The real price of your copy depends on condition, centering, gum and margins, so treat the range as a starting point. For a stamp that may be worth a lot, ask an expert for a certificate.
