I haven't really given much thought to this, but I notice a lot of time people will post a pic of a traditional knife along with a silver coin or coins. That got me to thinking about when I was a kid, older men would often (at least where I live)carry a coin along with their knife? Seems like a silver dollar. I haven't really seen this in years. It seems like we've replaced the coin with flashlights and such. Anyway, I was wondering the significance of this(I'm guessing a good luck charm)? And feel free to post some more pics of old pocketworn edc knives along with more coins.
