Apparently Margo's made "stickered silver dollars" which is odd for a little place "in the middle of nowhere."

But I'm guessing one of those dollar coins would be worth a King's Ransom. Look for one at your next swap meet journey, Jay!

As for who "Margo" might have been - I was once working on a lawsuit concerning an assault-and-battery action regarding a bar out in Lancaster - I don't remember the exact name but something vaguely gangster-related like "Spikey's Bar." So we asked an interrogatory, who is "Spikey"? (Hoping to draw out a name of an additional defendant to add to the suit.) And the sworn answer came back: "Our dog."
