The coin looks great and I'm looking forward to see what you (and the artist, by extension) achieve!

The case is made to obscure any form of radiation. The artist is actually a physician and is fully aware of that concern. (I specifically asked him about that myself.)

As far as the central authority you are correct, there is an initial trust factor, but in general, I am referring to the practice of having to continue to rely on a central authority to grant access to the private key (TitanBTC for example).

By the way, I have great respect for your work Mike. Thank you for what you have done for the bitcoin community. Your contributions have been substantial.

No more cheesy holograms.

Are you suggesting you've successfully achieved unbreakable physical security?

When you engrave characters to metal, this changes the metal's shape, making the characters clearly readable with pretty much any sort of reflective radiation.  The tamper proof case may look great but what if tampering is unnecessary because any physician can take it to work and see through the case with medical imaging gear?  An engraved secret in a metal coin is also going to be vulnerable to magnetic imaging techniques.

You do not have to trust a central authority with these.

Not even the maker of the coin?

A portion of each sale will be donated to the Bitcoin Foundation as well. These coins will be available at the next Bitcoin Conference in 2014. A limited amount of them will be available in November 2013 so if you are interested let me know and I will pass your info on. Remember, only 600 of these will ever be made in silver and this is the first coin and is a first edition. The artist is planning 50 different coins to be made over the next 3-4 years prior to the block reward reducing to 12.5 BTC.

The coins will have the private key engraved on the edge of the coin which will be hidden completely by a tamper-proof case. A proprietary cipher system allows verification that the case matches the bitcoin address engraved on the tails side of the coin. No more cheesy holograms. The case will ensure the private key is hidden. All coin cases are signed and numbered by the artist. Case is custom made and is similar to other clear/tamper-proof cases seen with other collectible coins. Bitcoins embedded will be cold stored. You do not have to trust a central authority with these. Bury it in the ground and in 1000 years it will still be good!

He made 600 of these. They will have 2 BTC embedded along with 2 oz of fine silver. He is a presidential sculptor and only makes limited editions.

I didn't make it actually. A friend of mine did.

To my knowledge, this is the first time that pictures of these coins have been released. I have been given permission to post these, so you guys looking now are the first to see them.

Look at this freshly minted 2BTC, 2oz silver coin with Adam Smith, father of modern economics:
