High-tech CertiLine BarCard® package protects the coin from tampering activities, making apparent
any forgery and counterfeiting attempts. When the BarCard® is opened, an unpredictable pattern will
be displayed on the internal surface of both card
halves. Undetected reuse or reassembly of the
package will not be possible.


Storing Bitcoin securely can be a challenge. Denarium aims to solve that. We make secure offline Bitcoin wallets. Call them Physical Bitcoin or Bitcoin coins. They are designed to help you save Bitcoin securely. For beginners and experts. The private key is always safely hidden under a security hologram.


We want to introduce you to bitcoin, and help you

invest in bitcoin securely. We make coins ranging

from very affordable to premium quality coins

made from brass, silver, and gold. Denarium

physical bitcoins are great gifts for family, friends,

and coworkers to introduce people to bitcoin.


You receive every coin with a bitcoin address and

private key in order to load bitcoin on the coin.

You can also choose to purchase bitcoin directly

through our site while making your coin order. We will then automatically load bitcoin unto your

Denarium coin once you receive your order.


As of this moment, 603 BTC (3,45 M€) is securely stored on Denarium physical bitcoin coins. Find your bitcoin coin balance anytime on our public database among 11702 coins produced. We make charts to show you our process and to be transparent.
