[Winner] Silver [Silver Details] In March, 2008 there was an unprecedented shortage of 'retail silver' (physical silver in forms that all but the largest investors typically purchase). Most large bullion dealers were out of most or all of their silver (and their suppliers were out, too) for a few weeks. Again, in August, 2008, major shortages occurred. This could be attributed to the silver market being small, but if shortages of retail silver haven't occurred in the past, it's a sign that either [1] there is less silver available than before, or [2] investors are purchasing more silver than in the past, or [3] dealers were reducing their inventory (which doesn't make business sense). As one of these shortages began, The Tulving Co started selling 1000 ounce silver bars, suggesting that it was one of the few forms of silver that could be obtained (they are rarely sold in the retail market). [Gold Details] There have been minor retail gold shortages, but not to the extent of the silver shortages. The argument that silver shortages occurred because the silver market is small don't help -- if the silver market is so small, it would take less investor demand to cause prices to rise. [Reason]
