Our Focus


Tired of paying a fortune for a Physical Bitcoin? No more. The key strength of Denarium Bitcoin is affordability. Our coins are gift items anyone can afford to give to friends and family. Purchasing is easy with Bitcoin, Altcoins or international bank transfers.


The compact size and simplistic design of Denarium Bitcoin give them great functionality. Redeeming the bitcoins from our coins is easier than ever since the private key inside the coin is printed not only as plain text but also in QR code format.


Our company is a pioneer in the Bitcoin industry and has been in operation since 2012. We operate multiple Bitcoin services. Our coin manufacturing and private key creation processes are strict and trustworthy.


The private keys are created offline with a secure random number generator. Only 1 key is printed per coin and the printer memory is wiped after each batch of keys. The hologram we use on the coin is a high quality custom made security seal.

Frequently asked questions

Where is the product manufactured?

In Finland.

Do you keep a copy of the private key?

No. We print the private key once and after printing we immediately destroy the source file and wipe printer memory. The keys themselves are generated on a computer that is always offline.

The process of assembling a Denarium Bitcoin is a highly supervised. Each phase of assembly that involves the handling of private keys is directly supervised either by Henry Brade (CEO) or Viljami Räisä (CPO), or both.

If you don’t want to take any chances, we now provide a trustless multisig option for some of our coins.

Which countries do you ship to?

Almost all of them. There are however restrictions on which products we can ship, depending on the country:

Europe: All products

North America

– USA: Only “Empty” products

– Canada: All products

South America: All products

Africa: All products

Asia: All products

Australia: All products

The reason we can’t sell coins with loaded bitcoin value to the USA is regulation. We can sell empty coins however which can be loaded by the customer.

If I order now, how long until I get the products?

Our dispatch estimate is 3 business days and the delivery time depends on the shipping method used.

Note! Backorder products have estimated 3-6 weeks delivery time. We process orders sequentially so sooner you order faster you receive.

How much does shipping cost?

Shipping cost is calculated by weight, products, and destination country. You can look at the shipping costs for the order after adding the products to the cart.

These are the starting prices for a one 29 mm coin. Some countries, cities and postcode areas may have a higher shipping cost.

Terms of Service

Current Denarium Terms of Service

Is there an affiliate program?

Yes! Login or register to see your referral link. Share your referral link to get rewards when purchases are made by visitors who came through it. You will get a coupon code worth of 2 EUR from every purchase. These coupon codes can be combined.

It is prohibited to make purchases through own referral link. If any violations are detected coupon codes will be deactivated and orders may be canceled.

Can I become a reseller?

Yes! We are in process of building a global reseller network that would enable the purchase of our coins with different payment methods and in physical stores as well. We have our volume discounts public on the product pages already but if you have something special in mind, please email [email protected]

What about a coin with 1 full bitcoin?

Our flagship product with 1 full bitcoin has finally arrived! Check out the Denarium 1 BTC.

Where does the name Denarium come from?

The name is based on the ancient Roman currency system Denarius. We simply switched the end because Denarius is commonly used already.

Do you sell 2-factor coins?

Yes, we do. For all of our new coins there is a multisig option which adds another level of security. When ordering with multisig enabled the coin becomes trustless and therefore extremely secure.

What is the activation and how to do it?

The purpose of the activation is to declare the condition of the coins. All L-series coins reported good will be funded within 24 hours. For the E-series coins, the activation just changes their status to the completed state on the Denarium Database. If coins are reported missing or damaged we will contact the customer to resolve the issue. If a customer does not activate the coins they will be activated automatically after 3 months from the purchase date.

To activate your coins please go to the activation page and fill in your Shipment code and Email code. You will receive your email code to the email address used in your order and shipment code with your package.

Activation is required for funding the coins in your order. Also, it allows you to give us feedback about your shipment. Activation of series E coins is not required but recommended because it helps us to improve our service.

How do I check status and balance of my Denarium coin?

Please use our status tool on the top bar with your coin serial number.

You can also use our official Denarium Bitcoin database. The database is a single file, coin.tsv which contains current status of all Denarium Bitcoins ever produced in tab-separated format.

How to buy them as a gift?

Method 1 (recommended): Order them yourself , complete the activation and give the activated coins personally as a gift in nice gift envelopes (can be selected on a product page without charge).

Method 2: Order them directly to the gift recipient. Please note, that it is highly recommended to make the recipient aware of the upcoming shipment. Some courier companies requires that the recipient receive the package personally. It is also noteworthy that the gift recipient is responsible for the customs duties which may be subjected to the shipment.

Is there a risk of the private key being damaged through peeling off?

It is not possible. The private key is printed in a high durable plastic paper. In addition to the QR code the private key is also printed in a text format.

How many years is the sticker expected to last?

The lifetime of the holograms should be dozens of years as we use the same type of holograms that earliest bitcoin coins that were manufactured in 2011 and they are in good condition still.

Where are the orders shipped from?

All orders are shipped from Finland.

How to spend bitcoins from the coin?

See our page Physical Bitcoins for detailed instructions.
