MySky Stamps: Identify & Value

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

New: the Digital Perf Gauge measures a stamp's perforations straight from your photo — renders measuring by hand obsolete 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. Free to start — a handful of free identifications every month; subscribe for unlimited plus bonus features From Big Sky Stamps — Helena, Montana.
