I believe the right thing happened - and kudos to the honest kid.
If workmen where in your home and found a 'stash' in the ceiling - it wouldn't belong to them.
In fact, not too long ago, didn't some workers find some coins and end up being prosecuted for not returning them to the owner of the home?
It's not like the kid got permission to metal detect.
We do some archeological digs, from time to time - we get to keep nothing - and that's fine - we aren't financing the digs, just enjoying seeing history coming to life, and being part of it.
