Own a piece of Bitcoin history – a genuine fine silver Casascius coin, commemorating the first major sports event to be sponsored under the banner of Bitcoin! I will be producing a limited edition 2014 Casascius “Coin-Toss” Coin for the Bitcoin St. Petersburg Bowl game to be played on Dec 26. This coin will be […]

If I were Apple, I would ban Bitcoin wallet apps from the App Store too. ¬†Possibly though, I would ban them for different reasons than Apple might have. Having Bitcoins on a mobile device that is used for surfing the internet and running general purpose apps is an unmitigated disaster waiting to happen for both […]

I have listed an original 1000 BTC bar on eBay, and it is ending in about an hour. The bar was made and funded in 2011 but has been redeemed. Proceeds benefit the Electronic Frontier Foundation.

Please beware of fakes. A 25 BTC fake coin was recently listed on eBay by a brand new eBay user tradus1980 (listing 281255345385). The photos look convincing but there’s no way this one is real. I reported it to eBay but my report was not acknowledged.

I am going to be resuming the sales of the aluminum coin (which does not have bitcoins on it). I am also planning to sell unfunded coins for 2014. These coins will have new visual differentiators so they can be distinguished from coins that are pre-funded by me. These coins will have usable (but empty) […]

They use a different type face for the main Casascius as well as a slightly different B-logo shape. My series 1 coins also […]

For the time being, I have suspended accepting new orders, pending resolution of some concerns I have as to regulatory issues. I am anticipating a possibility of having to prequalify buyers, and am holding off taking orders until I know for sure. This won’t affect any past orders.

The remaining 700 of the two thousand 1oz 1BTC silver Bitcoins I produced for 2013 now have gold plating on the B as well as on the rim. These were done with a newer process that is more thorough and solid as compared to the 2012’s. Since I have done this to the remainder of […]

I sent out the first funding of the 2013 silver coins, a large (47 kilobyte) transaction with 1295 txouts. The transaction fee was 0.005 BTC. Stated another way (USD), I just sent over $110,000 over the internet to what may eventually end up being over a thousand different people, without opening an account anywhere […]
