Out by the Pyramids there is a coin shop. I dunno if they would do just an even swap out of the kindness of their hearts...there might be a fee or something. Plus Indiana charges sales tax on PMs.
Not to derail the thread but when the SHTF, a brick of 22 LR will be much more valuable then silver? even gold will have minimal value. Did anyone hear Dave Ramsey on the radio today?
