About this app

Hold a stamp up to your camera and find out what it is. Perfin identifies postage stamps from a single photo, tells you the story behind each one and, with Pro, estimates what it is worth at every condition grade.

Identify a stamp from one photo
Take a picture or choose one from your photos. Perfin finds the stamp, straightens it and reads it: country, year of issue, design and history. Every match shows how confident it is. When a stamp could be more than one issue, you see the candidates side by side instead of a guess presented as fact.

Value it at every condition grade (Pro)
See an estimated value range for mint never hinged, mint hinged, no gum and used copies, each labelled with the grade it assumes and the date of the estimate. Values are AI estimates and say so. They are not appraisals or offers. You grade your own copy: Perfin never guesses condition from a photo.

Spot signs of a fake before you buy (Pro)
The authenticity report checks perforations, paper and print, and shows where your copy agrees with genuine examples and where it does not. It is a visual opinion, not a certificate, and it tells you when an expert's opinion is worth the fee.

Build your collection
Save the stamps you own with your own photo of each one. Grade them yourself and, with Pro, see what your collection is estimated to be worth.

Find the stamp from your birth year
Pick any year from 1840, when the first postage stamp was issued, to today and discover a stamp from that year.
