Hi!
on this board several times I have posted as well as Steph, an original salesman's catalog page with descriptions of specific marbles, aces included. But yeah, I agree, when it comes to money, lOTS of people don't care, and that's too bad. aces have an opal moonie ribbon through the base glass, that shines an opalescent pink when back lit. so it's really pretty easy to tell the difference. no fire in the glass? not an ace, just a translucent cork. which in itself is cool too, don't get me wrong, I like both!
