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.

I am using Priority Mail Flat Rate mailers - same shipping cost regardless of number of coins.

Most people order more than one coin (and possibly for the very reason you cite - it's not as cost effective to pay that for orders of single coins).

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

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

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!

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 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.

Why is casacius the only person that gets away with so many spam / ad postings on this forum?

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.
