silver is more spendable, when paper looses its value. i believe pre 1964 or so is the right silver content to seek in a dollar coin form, 90% or above as it can be best traded for a set amount say 90% of market value. its believed one coin a week will feed an average family, $20 or so.
i remember when we were kids we (found) a bunch of old paper money the bank was to destroy. we were not aware it was backed by gold and silver, we had rcmp's all over us, as we frantically spent a fortune in silver and gold bullion and turned it all into arcade tolkens.
even at the fair you could cash in your paper for silver dollar coins and half dollar pieces that were never seen in circulation at face value, for a crack at crown and anchors.
i finally recovered my password, wasn't even that hard either. lol
