I just thought of a new product I'd like to offer, and you can order it right now on my website for 0.13 BTC.  I will automatically treat any order of 5 or more "broken" coins as an order for roll-your-owns.

The "roll your own" Physical Bitcoin is simply a real Casascius coin without the hologram and without any funds.  Instead you get a fresh private key circle (so you can fund it) and a gold foil sticker to cover the key.

The big advantage?  CHEAP.  Especially in quantity, if you don't care about there being a Casascius hologram.  Perfect if you are trying to give BTC for birthdays or as freebies to others at the lowest cost, to someone who won't care about the lack of a hologram.

Simply order 5 or more of my "broken 1BTC sample" on my website.  Rather than receiving coins with a torn hologram, you will receive brand new fresh coins that have never been stickered.  You'll receive a sheet of gold stickers, and a pack of pre-cut private key circles to fit.  (I will typically provide a few extra stickers and keys than you paid for so you can feel free to test/ruin a few).

The circles are laser-cut and have the private minikey on one side and the firstbits on the other, and each one is unique.  To fund it, you look up the full bitcoin address via the firstbits from https://www.casascius.com/fulllist.txt.  Same policy as on my other keys - I do not keep the private key, for each key you get, it is the only copy that exists - you're also welcome to create your own keys if you feel inclined.
