In the first row, the middle one -- brown -- is a bennington.
The one on the right with light blue splotches and other faint colors is probably also a bennington. It would be called a "fancy bennington".
The rest are not benningtons.
The ball-bearing variety of steelie has a certain charm but pretty much no value. For most collectors the important thing to do with steelies is to make sure they aren't touch marbles they could damage. Probably futile to try to clean it.
