Gold coin Unicorn — Crypto Stamp Coin 2023
Gold coin Unicorn
The Crypto stamp coin of 14 December 2023 is the first coin whose NFT is activated directly through the coin itself. 999 pieces, 999 EUR retail price, 7.8 g fine gold (999.9 fineness, exactly one quarter ounce) at 22 mm diameter. The set includes a Crypto Stamp 1.0 Unicorn from Österreichische Post's reserve stock — a rare opportunity to obtain the sold-out original edition.
History
The Crypto stamp coin of 14 December 2023 transfers the Crypto Stamp concept (physical object + digital twin) to coin format. The NFT twin is activated directly through the coin itself — not through a bundled separate token or code. Österreichische Post expands the Crypto Stamp family with a coin product category.
The edition appears between two joint editions: 6 weeks after CS 5.1 Lion (trilateral, 10 October 2023) and 10 months before CS 5.2 Dragon (quadrilateral, October 2024). During this period, the Post experimented with new formats — the coin represents the format experiment of the CS series.
Concept: Coin as a Crypto Collectible
The choice to produce a coin (rather than another stamp) has strategic and aesthetic reasons.
Strategic. Coin collectors and stamp collectors are partly overlapping but distinct communities. The Post had established a position in the stamp market with Crypto Stamps — and used the brand strength in 2023 to expand into the coin market. Buyers of gold coins tend to be value-security oriented; the crypto NFT supplements their collection with a digital element without undermining traditional coin value.
Aesthetic. A gold coin has different materiality than a stamp. The tactile quality — weight, coolness, shine — is part of the experience. The Crypto stamp coin uses these properties to extend the crypto collectible from a flat stamp block to a three-dimensional premium item.
Product Specifications
The Crypto stamp coin shares the material connection to Münze Österreich with Gold Editions but has its own format:
- Material: 7.8 g fine gold, fineness 999.9 (corresponds to a quarter ounce in coin standard)
- Format: Coin, 22 mm diameter
- Motif: Stylized unicorn (homage to the original CS 1.0 Unicorn from 2019)
- Retail price: EUR 999 (matching the mintage size)
- Packaging: Premium presentation case
- Mintage: 999 pieces
- NFT: Digital twin on Polygon blockchain, activatable via personalized code
The 999 / 999 / 999 pattern (EUR 999 price × 999 pieces × 999.9 fineness) is semantically distinctive and positions the edition as curated brand communication beyond the usual Crypto Stamp repertoire.
The Set: Crypto Stamp 1.0 Unicorn from Reserve Stock
The Crypto stamp coin includes a Crypto Stamp 1.0 Unicorn from Österreichische Post's reserve stock.
Background: CS 1.0 Unicorn (11 June 2019, mintage 150,000) sold out weeks after release and has since been available only on the secondary market. Collectors could not directly acquire the original first edition from the Post anymore. The fact that the Post delivers CS 1.0 pieces in 2023 with the coin edition shows: the Post held back a reserve from the original 150,000-piece print — for future special editions or replacement stock for complaints.
The exact size of the CS 1.0 reserve has never been publicly communicated. A lower bound can be derived: at least 999 CS 1.0 pieces had to be available for the Crypto stamp coin. The reserve was likely somewhat larger to cover replacement stock for defective pieces — in the low four-figure range.
This structural uncertainty about reserve size has a consequence: the mintage 150,000 of CS 1.0 is not entirely accurate, since a portion was not immediately on the market but remained in the Post reserve for years. Collectors who research token IDs occasionally find CS 1.0 pieces from the 2023 coin wave with late activation times — a hint of reserve provenance.
Sales Trajectory: Crypto Winter Meets Premium Format
Unlike most Crypto Stamp editions that sold out within minutes or hours, the Crypto stamp coin remained available for over two years — until early 2026. This long sales period has several reasons:
High retail price. At EUR 999, the coin was twice as expensive as standard Gold Editions (EUR 500) and thus a heavier purchase decision for many collectors. This filtered the buyer base.
Crypto-winter effects. The edition appeared in the trough of the crypto market in 2023. Speculative buyers, who had ensured rapid sellouts in earlier editions (Golden Unicorn 2020, sold out in 20 minutes), were more cautious in 2023-24.
Format distinction. Coin collectors have different buying habits than stamp collectors. While stamp collectors often buy impulsively (while still available), coin collectors weigh more carefully. This slows the sellout trajectory.
Sales-trajectory anomalies. On 14 December 2023, the coin appeared sold out in the late morning but became available again throughout the day — due to cart expirations when buyers did not complete the order. This anomaly repeated on 15 December 2023 and in the following weeks.
The final sellout in early 2026 coincided with a gold-price increase that brought the coin's material value close to its retail price. At a gold price of around EUR 128/gram, the pure gold value of 7.8 g is about EUR 998 — practically identical with the EUR 999 retail price. At this point, the coin transformed from a collector item with a gold component to a gold investment with a bundled collector-value component — explaining the final sellout.
Collector Significance
The Crypto stamp coin holds a special position in the collector universe:
Format pioneer. First coin-with-NFT edition. Defines the format for possible future crypto coin editions.
Set character. The Coin + CS 1.0 Unicorn combination makes every set a mini-collection with two standalone collectibles. Collectors interested only in the CS 1.0 Unicorn must accept the coin — and vice versa.
Historical significance. Connects the original CS 1.0 Unicorn (first edition 2019) with the coin innovation (2023) in a single product. Represents the continuity and evolution of the Crypto Stamp brand over the first 4.5 years.
Secondary market. Due to the late sellout phase, the coin is more available on the secondary market than earlier premium editions. Prices typically range between EUR 1,000 and EUR 1,400 — the premium over retail is moderate and reflects greater market availability. Collector-preferred token IDs or sets with particularly well-preserved CS 1.0 command premiums.
Position in the Program
Programmatically, the Crypto stamp coin belongs to the Gold Editions family (program 'gold') — with physically embedded precious metal, high premium character, and small mintage. At the same time, it is the only coin-format product in the Crypto Stamp series so far and stands in its own format-historical context. As the first coin with a digital twin on the blockchain, it has a distinction comparable to the Golden Unicorn 2020 (Guinness World Records: highest issue value of a digital stamp) — both editions hold record-setting distinctions.
Frequently Asked Questions
What is "the first coin with a digital twin on the blockchain"?
Crypto stamp coin transfers the Crypto Stamp concept (physical collectible + NFT) to a coin rather than a stamp for the first time. The 7.8-gram gold coin carries a personalized code with which the buyer can retrieve the digital twin on the blockchain. Before 2023, there were coins with bundled NFTs, but none whose NFT was activated directly through the coin itself.
What does the included CS 1.0 Unicorn mean?
With every Crypto stamp coin, a regular Crypto Stamp 1.0 Unicorn is also delivered — from Österreichische Post's reserve stock. This is historically notable: CS 1.0 appeared in 150,000 pieces in 2019 and sold out within weeks. The Post must have held back a small reserve that was made available again in 2023 for the coin edition — a rare access to the long-since unavailable original edition.
What reserves did the Post hold back?
The exact size of the CS 1.0 reserve has never been publicly communicated by Österreichische Post. From the fact that each Crypto stamp coin is delivered with a CS 1.0, however, a lower bound can be derived: at least 999 pieces must have been in reserve. Realistically, the reserve was likely somewhat larger to cover replacement stock for defective pieces.
Why was the coin available for so long?
Unlike most Crypto Stamp editions that sold out within minutes or hours, the Crypto stamp coin remained available for more than two years — until early 2026. The high retail price of 999 EUR significantly limited the buyer base. Additionally, the crypto winter of 2022-23 dampened speculative appetite, and the coin format addressed a different audience than the classic stamp collector community. The final sellout in early 2026 coincided with a gold price increase that brought the coin's material value close to its retail price.
How does the gold price affect the value?
The Crypto stamp coin contains 7.8 g of gold at 999.9 fineness — corresponding to 7.7922 g of fine gold. At a gold price of 75 EUR/gram, the pure material value is about 584 EUR; at 100 EUR/gram, 779 EUR; at 128 EUR/gram, 998 EUR (= retail price). In early 2026, the gold price reached levels at which the coin's retail price was covered by material value alone — explaining the final sellout: buyers no longer bought the coin merely as a collector item but as a gold investment with a bundled collector-value component.
