Physical bitcoins have been around for years, but they are anything but mainstream and there are very few companies involved in this fledgling industry. Some try to appeal to consumers through quality and the use of precious metals, others offer good designs at relatively low prices, while some offer neither.
The market for physical coins is limited and this is a niche for collectors and diehard enthusiasts. The limited size of the industry is a problem, as a number of firms have already gone out of business, while others never even started shipping their products. If beauty is in the eye of the beholder, then, while there are some truly spectacular designs, others may not impress most users.
Caldwell started minting his coins a couple of years ago, but late last year he was banned from selling pre-funded coins. In addition to these silver, brass and gold-plated products, Casascius also sells aluminium promo coins. A bag of costs 0. They are pure silver coins and weigh two ounces.
Both coins were designed by presidential sculptor John B Andelin. Only coins of each series were struck and the pricing reflects the exclusivity. The Adam Smith coin is priced at 2.

Although they are not physical coins with QR codes and holograms, they still make for an unusual bitcoin-themed product. The kit includes a coin, two security holograms, a pouch, display stand a few other goodies. Each coin is individually numbered. Like Antana coins, CoinedBits are novelty items with no bitcoin value and they are not physical wallets.
The coins are 38mm in diameter, 3mm thick and weigh one ounce. The material is pure brass with karat gold plating. A four-coin silver bitcoin set is available 0. There were a number of physical bitcoin projects that never amounted to anything. Most are either defunct or delayed. Although they never got off the ground, some them had certain features that make them stand out from the crowd.
A Chinese bitcoiner minted a small batch of one-ounce physical coins and the images were posted on the 8btc. The coin weighs one standard ounce rather than one troy ounce and is made from karat gold.
The current status of the project is unclear. Alderney, one of the British Channel Islands, considered launching a physical coin of its own. Plans for a physical coin were announced late last year, but appear to have been shelved for the time being. There is another way of getting your hands on a physical bitcoin — make one yourself. There are a number of print-ready 3D designs out there and they are just a Google search away, usually on 3D print marketplaces like Shapeways.
The trouble with this approach is that most designs are relatively expensive, even before you include the cost of actually printing them. While it is relatively cheap to do a few plastic prints on semi-professional fused-filament printers, making a proper metal coin on an expensive laser-sintering printer tends to cost a lot. In any case, 3D printing is an alternative way of producing unique physical coins by tweaking existing designs or developing your own.
One example of an affordable design that relies on nylon plastic with a matte finish is the Bitcoin Address Keeper by Ayame Deude.

Last Updated on December 1, Most of us have probably been asked that very same question on more than one occasion. People might be willing to spend money with a swipe of their card but the idea of a currency that exists in a permanently ephemeral state is a leap of imagination they are not prepared to take. The coins certainly look the part and yet, some explanation of how exactly they work is required before the uninitiated can truly grasp them on even a conceptual level. The value of the coin is displayed on the front in Bitcoins; currently the company offers values ranging from 0. The latter figure is to those unversed in their use, just one point of potential consternation. The reality of course is less dramatic. The coins come with a public key visible on its back face allowing you to verify its value simply by opening a new wallet on the blockchain. The private key is hidden beneath a tamper — proof hologram, that is to say, a person could with some effort get at the key but it would be immediately clear that somebody had done so. A stolen or lost coin could not be easily sold on to a third party with its bitcoin value included in the price without being able to demonstrate that you had access to the private key.
