Just thought I'd post some of the keys I found last year, I have some skeletons too, but they are already packed up. I'll try to post pics of them later
I think I found the lock to one of your keys but have already thrown the rusty thing away. I find a lot of keys myself. Not sure what exactly to do with them so they just pile up.
Now if you can just find the safe that they go to. Just kidding. I find quite a few keys myself. I think they're fun to dig up. I just don't know what to do with them yet either. Good luck in your future detecting.
