>>1456377>everything you've found in a mine is way more common outside of a mine.and that's ultimately the problem with finding stuff in mines. Your lighter sells for anything from $45-$100 on ebay, so anyone with a few bucks to spend could get one and take it into a mine and say "Look what I found!" So where you found it doesn't add anything to the value, you're the only person that knows for a fact you found it there. Even pics of it inside the mine aren't proof of anything, because again anyone that wants to could take one in there and shoot some pics of it.
So all you've done is taken a fairly ordinary artifact from a somewhat extraordinary context in such a manner that it can never again be proven that's where it came from. Or, as archaeologists would say, you've destroyed the historical context of the find. Or as collectors would say, you've destroyed the provenance of the find. Which is fine, it's just trespassing and theft. But to pretend your rather ordinary and often worthless junk which is only interesting because of where you found it continues to be interesting to any reasonable adult on that basis is absurd. What you've actually got is a box of antique trash that used to be interesting right up until the moment you moved it. After that it's just junk.
Here's an example of exactly what I mean. 2 old blasting cap tins. One was found in a mine and is worth $0. The other was found on ebay and is worth $25. Aside from me, nobody knows which was found in a mine, nor would anyone care. It was a cool find, but I'm literally the only person that knows where I found it. To anyone else it's just trash. It's old trash, but trash none the less
