A bar printed The Washington mint 1 ounce .999 fine silver what is the value?

Currently as of 2/11/2009 the spot (wholesale price of silver) is about $13.50 so if you were to sell it you can probably sell if for somewhere $13.50-$15.00 in today's market. If you were to sell it on eBay you can probably get a couple of more dollars yet the fees and shipping will use up the difference. The market at this time is unusual in that a high premium is being paid for .999 Silver bars and rounds. In more normal circumstances a coin dealer might pay you spot price or less. Today you can get at least spot price or better.
