Found this in a hole i was digging while detecting in VA. Didn’t look like any other rock I’ve ever seen here. I swear the outside looks like bark to me... might be crazy..
If it registered as containing metal then it could be slag or similar trash. If your real lucky it could be a meteorite. Those can be worth quite a bit. I don't actually know what it is though.
Does it set off the detector, or was it just dug up while searching for a metal object?
