From the pictures the Blue Devil is probably nm- to maybe near mint condition. In hand or with a loupe probably nm- or less. I cannot count all the hits and scratches. Single out that marble and take close up, macro, 10x pictures and the damage will appear. Look at it with a 10x magnifying glass. Most experienced collectors when buying $25.00 individual marbles and higher will check them with 10x magnification. When I list marbles for sale on Ebay, I use macro 10x on my camera for all my pictures.
Vitro Blue Devil mint range condition = $ 30.00- $50.00, near mint range = nm- $10.00, nm $20.00 - nm+ $25.00.
