Digital currency was never meant to be seen — only recorded. Yet in 2011, the original Casascius Bitcoin changed that idea forever. Created by Mike Caldwell, the Casascius coins were designed to give invisible digital value a physical form. At a time when Bitcoin was new, confusing, and difficult to use, the concept was simple: embed real value into a tangible object that could be held, gifted, and collected. The coins became iconic not just because of their design, but because they made something abstract feel real.
Production ended in 2013 after U.S. regulators required Caldwell to register as a money services business. Pre-loading value onto physical coins had begun to blur the line between art, currency, and financial custody. Today, original Casascius Bitcoins are highly sought-after collectibles, often worth far more than their original face value.
The Kasascius Coin takes inspiration from the original idea, but reimagines it for the modern era. Today, users are fully capable of creating their own wallets and securely managing their own keys. Trusting a third party to generate or control private keys is no longer necessary and for many, no longer acceptable. That's why Kasascius removes trust from the process entirely.
Before purchasing a Kasascius Coin, the buyer creates a fresh Kaspa wallet and provides only the public wallet address. No private keys are ever shared.
That address is then:
This allows the buyer to independently:
Nothing is hidden. Nothing is custodial. Everything is verifiable.
Once the coin arrives, the buyer sends the Kaspa to the address they provided. Now, when you scan the QR code on the reverse of the packaging, it will show your address, which you can run through an explorer and see the corresponding Kaspa amount in that wallet.
At no point does Kasascius generate, store, or have access to private keys. The coin is a physical representation of an address, not a container of secrets. This design removes all reliance on trust while preserving the symbolism and permanence of a physical artifact.
A Kasascius Coin is more than a collectible — it is a physical anchor for digital value. A meaningful way to gift Kaspa. Instead of sending an invisible transaction, a Kasascius Coin turns Kaspa into something tangible, personal, and memorable. A long-term holding format. The engraved address and verifiable balance make the coin suitable for holding a fixed amount of Kaspa over time. A modern collectible.
Inspired by the legacy of Casascius, but designed for a transparent, self-custodial future. Verifiable at any time. The address can always be checked on-chain. Ownership is provable without opening the package. Digital Value, Made Physical.
Kasascius Coins sit at the intersection of technology, design, and philosophy. They don't replace wallets — they give digital ownership a physical form.
In a world where value is invisible, a Kasascius Coin gives Kaspa something rare:
presence, permanence, and proof.
