I am planning on selling Gold and Silver bullion via the Global Bitcoin Stock Exchange (GLBSE) http://www.glbse.com
Current plans are to offer contracts for 5 1oz silver rounds with plans to sell 1oz, 10oz and 100oz bars. As far as gold products go, I am looking at offering American Eagles in various denominations. Price would include shipping and insurance to anywhere in the US. I am still investigating options for international shipments.
The first product to be offered will be lots of 5 of the buffalo 1 ounce rounds shown below.
