Stamp-Manager now offers a new feature for those who want to catalog their stamp collection in just a few minutes and share it with a global collector community for offers. This allows users to quickly get an estimate of the value of their stamp collection. For valuable stamps, we recommend: "Request a professional appraisal." Here, neutral philately professionals determine the current value of the stamps, taking into account information such as recent auction prices! Maybe you own such a treasure and don't even know it? Finally! The app for stamp owners who want to quickly get an appraisal for their collection without needing detailed knowledge of the stamps is here! Scan your album and make it available for a worldwide community appraisal, with over 80,000 participants. This way, you get the first estimates from over 80,000 registered users and can decide whether to sell your collection at the offered price or not. If the community identifies a valuable stamp in your album, and you want to obtain a neutral, professional opinion on the value of the stamp, then use our "Professional Appraisal" offer. Within a few days, you will receive an official appraisal of your collection, or individual stamps, from a philately professional. You can use this appraisal for an offer to the community or offer the valuable stamps through another auction house! We are happy to advise you in this regard. Stamp-Manager Subscription: With a Stamp-Manager subscription, you have the ability to upload an unlimited number of albums and images. You can also use the Stamp-Manager ad-free.

About

Read full description

Since 2021, Philately Liechtenstein has been issuing postage stamps with blockchain technology from the Principality of Liechtenstein. These stamps are forgery-proof, interactive and exciting. Deposit your postage stamp in this app and find out which collectible is hidden behind your stamp. Each stamp contains a digital puzzle piece that only becomes visible after scanning it in the app. But that's not everything by any means. You can also solve puzzles, improve your best time and and compete with other users worldwide. Stay active and collect points to constantly improve your ranking. Our "Fantastic Animal World" small-sheet series can also be deposited in the app and will welcome you in their own language - so sound on! You have all stamps and want more? Find our Easter eggs (QR codes) and scan them to discover more about the world of stamps. Have you already searched on our website? The valid postage stamps can be used for mailing just like any other stamp. On our "Stamp 4.0" and β€œStamp 4.1” an SQR-code is also integrated. When the SQR-code is scanned with the matching app, the stamp becomes visible as a digital twin in the app and can be placed in your digital collection. This gives your stamp a digital CV. These innovations make the Stamp 4.1 forgery-proof, interactive and exciting.
