UPDATE:

Two days after I posted about this in this forum and on reddit, I was contact by Justin at GoldSilverBitcoin with a promise that a coin would be in the mail within 48 hours. Eight days later the single American Silver Eagle coin I ordered 5 months earlier finally arrived. I have the full review of this experience at http://buygoldwithbitcoin.com/

By this transaction Justin has unfairly profited at my expense in the amount of around 100 dollars, since if I had held onto the bitcoin during this time, I could have bought five silver ounces today instead of one. So he enjoyed the value of the bitcoin payment I made going quickly up in value as he held onto it while ignoring my emails for another 75 days, and didn't ship the coin until I made this public. I am not happy with this company GoldSilverBitcoin.
