Mint Coin Set

What Is a Mint Coin Set?

A Mint Coin Set is a collector item in which a crypto stamp and a coin are united as an inseparable set — manufactured in cooperation between a postal service and a state mint. It is a cross-industry innovation that unites two tradition-rich collector worlds (philately and numismatics) in the crypto stamp format.

First Application: CS Digitalisierung 2025

The first mint coin set in crypto stamp history is CS Digitalisierung of 12 March 2025:

• Set components: 25-euro silver-niobium coin + crypto stamp (€21.80 face value)
• Set price: €121.40
• Mintage: only 5,000 sets (very limited)
• Mint partner: Austrian Mint (founded 1989, successor to k.u.k. Hauptmünze 1397)
• Postal service: Austrian Post

Structural Innovation

Mint coin sets establish several premieres at once:

1. First crypto stamp + coin set worldwide
2. First coin on blockchain: digital twin of the coin via certificate number
3. First crypto stamp with real silver: in the security pigment of the stamp
4. Double NFT mechanic: coin + crypto stamp each with own NFT
5. Cross-industry cooperation: state mint + postal service

Double NFT Mechanic

A characteristic property of the mint coin set: both components have an NFT:

• Coin NFT: accessible via the individual certificate number
• Crypto stamp NFT: accessible via the token ID
• Both on the Polygon blockchain

Collectors can manage both components independently on the blockchain or maintain them as a connected set.

Strategic Function

Mint coin sets tap two collector pools simultaneously:

• Crypto stamp collectors: familiar with the CS format, looking for experimental variants
• Coin collectors: classical numismatists, are guided into the NFT world through the crypto stamp component

This cross-pool tapping makes mint coin sets strategically valuable — both providers (mint and post) expand their collector base.

Premium Positioning

At €121.40 set price (vs. ~€9-10 for standard CS), mint coin sets are significantly more expensive than regular crypto stamps — they specifically target premium collectors.

Structurally similar premium concepts:

• Cross-Country Gold Edition (see corresponding glossary entry): 1g gold component, €500
• NL Gold Edition (30.11.2023): 111 pieces, also Austrian Mint partnership
• AT Gold Edition Dragon (25.06.2024): with Austrian Mint

Pioneer Function

The CS Digitalisierung 2025 is a structural model for future cross-industry crypto stamp cooperations:

• Other state mints could emit similar sets
• Other industry partners (e.g. precious metal manufacturers, universities) could initiate cross-industry sets
• International mint coin sets (e.g. with Austrian Mint + foreign postal service) are conceivable

The mint coin set thus marks a maturity phase of the crypto stamp format — expansion beyond pure postal service themes.
