Does anyone have interest in Copper Bullion or already collect? Do you feel that this could be a low cost barter coin if our paper goes belly up? I have seen local communities in the east start their own currency already (i.e. townships and counties), which is 100% legal. The US allows the manufacturing and use of custom currency for anything which is not a Dept... I am in the air on this one, but the cost is so low... Sort of thinking about it?
