Good points,

Personally myself not being in the U.S. i dont really expect i would want my bullion.
Ill just sell the coins on the market and take my btc.. go buy some bullion around the corner i guess. 

If the coin is backed by the asset.. then good enough.
I think a decentralized exchange would be ideal for something like this.

Any exchange is good at this point.. with weeks of prep, devs you should already have some exchanges on board and ready.
Looking forward to a week filled with communication and updates!!!  then i will throw more hash at this..

Also devs.. have an interview lined up for you ready to go with a popular crypto news/mag site.
