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

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](https://bitcointalk.org/Smileys/default/wink.gif)

Any significantly advanced cryptocurrency is indistinguishable from Ponzi Tulips.

And then you also just give away those private keys in the video to anyone with Mission Impossible Video Enhancement. ![Wink](https://bitcointalk.org/Smileys/default/wink.gif) 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.
