I have dug many over the years but never keep any of them, always looked at them as junk I guess.
After thinking it over I now wish that I would of kept some of the keys I have found. Each key has history to it, I just never gave it any thought until your thread. Thanks for starting the thread, I am really enjoying seeing the keys that you all have found.Since I only have been at this a few months, even the junk targets have some meaning, so I keep them all.
Something learned, a hole dug, effort expended, wasted or not.
I know I am going to make some kind of display with all this stuff, eventually.
