Watcha gonna do when the travelin' traders come through your town with extra eggs & honey, which you want, and they are only takin' payment in nickels? You gotta think outside the box. No one is saying to put all your preps into nickels. But it would be wise to consider keepin' a small bag of nickels alongside those extra cases of toliet paper.
I agree with having a diverse plan...but let's play it out for friendly discussion sake.
My question: Why would the merchants be taking silver content US legal tender coins in trade? What inherent worth do they have in a collapse situation?
