These coins look great, my friend sent me a picture of them while he was at the NYC Bitcoin convention a week or so again and I've been mulling over picking up a tenth, half and one BTC coin in silver.  Does anyone know if there are any coupon codes floating around?  

Edit:  Just read the thread, any news on the possible implementation of your 2FA scheme on the block chain itself?  I've got my order sitting in the cart, but I'm worried that what if something happens and Titan has to shutdown. What would be the protocol for making sure everyone with 2FA gets their private keys?
