MySky Stamps: Identify & Value

Point your camera at a stamp. MySky tells you what it is, what it's worth — and now, the perf measurement.

NEW — THE DIGITAL PERF GAUGE
Perforations decide a stamp's catalog number and often its value, and measuring them by eye against a paper gauge is slow and easy to get wrong. MySky does it from your photo: identify a stamp and you'll see its measured gauge right on the result, like "Perf 11 x 10.5 · sheet stamp." It's a real measurement of the teeth in your picture — the kind of tool no other stamp app puts in your pocket.

IDENTIFY ANY STAMP
Snap a photo and get the country, year, Scott catalog number, and a clear read on condition in seconds.

KNOW WHAT IT'S WORTH
Every identification comes with a Big Sky Market Valuation, so you can tell a $5 stamp from a $500 one before you buy or sell.

BUILD YOUR COLLECTION
Save stamps to your MySky library, see a running total value, and keep your whole collection in your pocket.

SELL WHEN YOU'RE READY
Send your collection straight to eBay, as live listings, right from the app.
