Cassius

Cassius, depicted as the antagonist in the Crypto Stamp Island series, appears on this stamp in five color variants distributed according to a scarcity pyramid. The Schwarz (black) variant accounts for 3,925 copies, followed by Grün (green) at 2,000, Blau (blue) at 1,000, Gelb (yellow) at 500, and the rarest Rot (red) at just 75 copies. Each physical stamp was sold at face value, €9.90, continuing the standard pricing model of the Crypto stamp program. The character design builds on the ongoing comic narrative that had been serialized through earlier releases in the Battle of the Mirrors storyline.

Österreichische Post supported the release with a creepypasta-themed marketing campaign, leveraging internet horror storytelling conventions to promote the antagonist character. The campaign included a comic sequel that expanded the lore of Crypto Stamp Island, positioning Cassius within the evolving fictional universe. This narrative approach marked a departure from the philatelic focus of earlier editions, emphasizing transmedia storytelling and genre fiction to engage collectors beyond traditional stamp audiences. The blockchain mechanics and contract details for this edition were not publicly disclosed at launch, leaving open questions about on-chain provenance and secondary-market verification.

The November 2025 release date placed Cassius late in the calendar year, a scheduling choice that allowed Austrian Post to close out the year with a villain-themed edition. The five-tier color hierarchy mirrored distribution strategies seen in previous crypto stamp issues, though the total mintage of 7,500 represented a relatively modest supply compared to some earlier mainstream releases. Collector reception focused on the scarcity of the Rot variant and the integration of the character into the broader Battle of the Mirrors arc, with secondary-market activity reflecting interest in completing the full set of island characters.
