Lion — Crypto Stamp 5.1

About the Austrian Variant

Crypto Stamp 5.1 Lion is the Austrian variant of the trilateral Crypto Stamp joint edition. Numerically, it sits between the Bear edition (CS 5.0, June 2023, Austria-only) and the Dragon edition (CS 5.0 in NL/LU/BE numbering, April 2024, quadrilateral). The 5.1 designation indicates that Österreichische Post sees the Lion edition as a follow-on generation to the Bear edition — both belong to the 2023 crypto year, with Lion internationally positioned.

Design Specifics of the Austrian Variant

CS 5.1 Lion shows the lion looking left — a design choice by Sandra Smulders, who assigned each of the three national variants a different gaze direction to create variation within the unified brand concept. The background is the red-white-red Austrian flag with embossed crystal structure — a visual reference to the blockchain.

Unlike NL and LU, the lion has no direct anchor in Austrian heraldry; Austria's heraldic animal is the double-headed eagle. The Lion edition therefore stands in Austria for the international crypto significance of the lion as King of the Beasts and as a connection to the joint-edition family. This asymmetry makes the AT variant less nationally symbolic than the NL and LU variants, but more strongly anchored in international collector logic.

Layered Design and Hidden Background

The stamp block consists of multiple superimposed design layers that produce different visual accents depending on light incidence and viewing angle. This multi-layer technique was discovered during the design process and has since become the standard for follow-on editions — through to CS 5.0 Dragon (2024) with its rainbow-foil effect.

When the three Lion stamps (CS 5.1 Austria, NL Crypto Stamp 2, Cryptostamp 1.0 Luxembourg) are physically placed side by side, a shared background emerges that is only fragmentarily visible on each individual stamp. Collectors who own all three variants can complete this hidden set effect.

Technical Platform

CS 5.1 Lion retains the technical foundation of CS 4.0 Bull and extends it:

• Blockchain: ERC-721 token, minted on Ethereum, primary transaction sidechain Polygon
• NFC authentication: 384 bytes AES-SUN NDEF encryption
• Augmented Reality: NFC scan activates AR animation of the lion in the smartphone browser
• Material: Invercote Creato matt 240 g/m², PET film, silver metallic, film printing and varnish
• Format: 43 × 53 mm stamp, 53.98 × 85.6 mm stamp block (ISO bank card format)
• Production: Variuscard GmbH, Vienna — same manufacturer since CS 1.0 (2019)

Companion Edition: Crypto Stamp Safe

In parallel with the Lion edition, Österreichische Post issued the Crypto Stamp Safe in three symbol variants — Pacifier, Bottle, Rainbow. These Safe stamps can morph one-time and irreversibly with the Lion NFT, transforming the Lion motif:

• Pacifier morphing: Lion → baby lion in neutral color
• Bottle morphing: Lion → baby lion in the original color (red lion → red baby lion, etc.)
• Rainbow morphing: Lion → rainbow lion, regardless of original color

This morphing functionality is a first in Crypto Stamp history and introduces a collector mechanic.

Secondary Market

CS 5.1 Lion circulates on Delcampe, eBay, Catawiki, and through specialized stamp dealers (Borek, Tyrol-Phila, Nordfrim). Black variants typically trade between EUR 30 and EUR 90. Green and blue variants command premium prices. Red lions achieve collector prices in the low four- to five-figure EUR range, depending on condition and special factors such as token-ID patterns.

Matched sets of all three Lion variants in identical color are particularly sought after — a collector incentive amplified by the hidden set effect.

Position in the Series

CS 5.1 Lion marks several turning points in Crypto Stamp history: scaling joint editions from two to three postal services, introducing the designer competition as a curatorial model, establishing layered design as the standard, debuting the morphing mechanism through the companion Crypto Stamp Safe. It is the step from bilateral exception to replicable multilateral format, paving the ground for the subsequent joint editions with Belgium (CS 5.0 Dragon, 2024) and Portugal (Mythologie 2025).
