I have no clue. Marble King made some bright UV marbles which were nearly clearies in modern times, but they didn't look like that.
All I can do is bump the thread.
Here is a video of an eaglet flying out of its nest tree for the first time. Happened last night. Now it is a fledgling.
It's part of the Decorah family of eagles. https://www.raptorresource.org/birdcams/decorah-eagles/
As to value, I'd think as a general rule knowing it's dug could lower monetary value. But I think the lines are probably blurred. If a marble is only known from the digs, and if not that many of them are known, then different rules would apply.
I don't know how to answer that. Probably a lot of dug ones you wouldn't be able to tell. But those colors are like a "spotted leopard" ... but without the spots. The spotted leopard is a fairly well known dug marble. http://marbleconnection.com/topic/9425-dug-leopard/
Here's an earlier dug marble example Lizzy posted with somewhat similar coloring, which was ID-ed as a spotted leopard.
Very important step accomplished -- I found my stash of marbles that I'm willing to send down a marble run. That can be difficult for a marble collector to do -- send little glass orbs into a situation where they're going to get knocked into each other. But I've found my marble run marbles.
