Casascius coins are unique in that they have a hologram sticker on the back, which conceals a private key. The private key is necessary to access the corresponding digital Bitcoin stored on the blockchain. This feature allows the physical coin to securely hold the value of the digital currency it represents.
The physical aspect of Casascius coins makes them popular among collectors and enthusiasts, as they combine the tangibility of a traditional coin with the value and potential of cryptocurrency. However, it's important to note that Casascius coins are no longer actively produced due to regulatory concerns. Nevertheless, existing Casascius coins continue to be traded and sought after in the cryptocurrency community.
