If you buy a contract for silver, you can get silver or cash when you sell the contract. Today silver spot price is 35 bucks per ounce, but the COMEX is willing to pay people 50 plus bucks per ounce if they are willing to settle for cash in lieu of the physical silver metal. In theory every contract sold by the COMEX should be backed by silver, but there is 100 ounces on paper contracts sold to and held by investors for every ounce of physical silver in the COMEX vaults. What happens when more people want the physical metal in lieu of the declining value of US dollars??? That is starting to happen as more people are concern with the devaluing US dollar. COMEX may not have enough silver on hand to meet its customer demands.
The current spot price of silver is based on numbers 100 times the actual physical supply available. Imagine what the price of silver would be when the public finally understands that the actual number of silver available is 1/100 the numbers quoted by the COMEX and banks.
... in other words: Got silver?
