Companies claiming they got hacked and lost your coins sounds like fraud so perfect it could be called fashionable.  I never believe them.  If I ever experience the misfortune of a real intrusion, I declare I have been honest about the way I have managed the keys in Casascius Coins.  I maintain no ability to recover or reproduce the keys, not even under limitless duress or total intrusion.  Remember that trusting strangers with your coins without any recourse is, as a matter of principle, not a best practice.  Don't keep coins online. Use paper wallets instead.

Reminds me of folding 10,000 flyers for my college prep school in Korea. That was fun.

May not be fun, but keep in mind I am charging about $2 for each coin

Just interested how do you keep track of private/public key pair? Does the paper circles have public key on one side, private on another?

I am essentially advertising giving away the ability and knowledge to make physical bitcoins to others, far more so than advertising to others to come buy mine.  A subject more of "open source" interest than typical ads.

I cannot satisfy the true demand for physical bitcoins making them myself, so I charge an inflated price to balance the supply and demand.  I am looking to encourage well-qualified others to make these at a profit.

I use a database that tracks the funding status and denominations of the coins.

One simple script queues the coins for activation using a firstbits lookup. The database knows what addresses I have generated, and can auto reject typos.

Another script produces a "sendmany" script for bitcoind to actually send the BTC out (I paste it into a shell window).  Using sendmany allows for bulk funding of coins in a single transaction, cutting out complexity and transaction fees.  The full bitcoin address is pulled from the database so I never have to type any more than the firstbits.

Another script sets aside a batch of coins for later funding. This is used for international orders. When the orders arrive, I simply throw their coins into the activation queue.

And then you also just give away those private keys in the video to anyone with Mission Impossible Video Enhancement.  Wink

Any significantly advanced cryptocurrency is indistinguishable from Ponzi Tulips.

The only glitch being that the private keys are face down - what is face up is a repetition of the firstbits.

Unless of course, the equipment can zoom in so well as to see the private key through the paper.  BUt then again, the coins have a window you can see through even on a completed coin, so just do the same thing on a completed coin and you'll have hacked it!

I wonder if there is any interest in coining alternate block chains like namecoin?

If you don't mind me asking, why is it that shipping costs $6 for one coin?

If the shipping didn't cost so much I might be more inclined to purchase one.
