When paper money becomes worthless silver will not do you any good either. The only valuable item at that point will be food. I know personally I could give a shit less what rare metal you have. It wont make me want to sell you my food for a chunk of shiny metal.
Good luck on investing tho. There is money to be made if you bought silver last year. I think it was 13-17 dollars at the time. At 36 sounds pretty high. It is a non renewable resource.
