I thought they were all birds of the same feather...
That is to say different names for the same type marble.
I seem to remember many were dug. Maybe others will chime in.
Don't worry... one Ebay...that would be Mint with just a pin flake on the back. LOL
Very Nice Pattern on it!!!
Edit: Maybe my comment of condition could be taken several ways....
It was just a joke. Nice Marble... & I Just saw it on Ebay.
I like to attend the "In Room trading" many shows have in the days before the show.
It is very relaxed and you can learn a great deal.
Do not be afraid to ask questions.
Most collectors love to help & talk marbles.
Have Fun!!
