Gold is often a tricky sell online unless it is assayed or serialized like how PAMP ships.  It is much more cost effective to counterfeit gold then it is to counterfeit silver (not implying yours are fakes).  Right now my local coin shop is selling 1 oz rounds for about 1 bitcoin over your asking price and in my opinion I would rather buy local from a known source at that price difference.  Just my two pennies worth.
