Denarium physical bitcoins, also called Denarium bitcoin coins, are physical bitcoin coin wallets created by a Finnish Bitcoin company Prasos (Prasos Ltd, Jyväskylä, Finland) that contain an embedded piece of paper with digital Bitcoin value, covered by a tamper-resistant hologram. Denarium bitcoin wallets are available in different BTC increments. They can be purchased at Denarium's website, https://www.denarium.com (multiple payment methods accepted: Bitcoin, Visa, Mastercard, IBAN/SEPA bank transfer).
The bitcoin wallet is designed such that they could be circulated in face-to-face transactions. The first person to redeem its private key gets the value on the coin, and afterward, the coin no longer has any Bitcoin value. It is difficult or impossible to read the private key on the coin without damaging or destroying the hologram, which exposes a honeycomb-like tamper-evidence pattern when peeled.
The piece of durable paper inside each coin has a private key which forms the backing for the Bitcoin value represented by the coin. The private key is in 30-character mini private key format. Redeeming the private key back into digital Bitcoins is currently available with a patched reference client as well as with many alternative clients such as Mycelium.
Denarium bitcoin coins are similar to Bitbills and Casascius physical bitcoins in that they are an object that contains a redemption code that serves as a bearer item for digital bitcoins.
