Overall a lot of commons.
The solid color ones are called game marbles.
The transparent ones are called clearies.
And you have a lot of cat's eyes.
This picture has the most moderately interesting ones, but nothing is standing out to me. If you broke it up into lots which conveniently fit into a small priority mailers you might be able to get up to $100 for even the commons on ebay. Maybe others will see some worth pulling out and giving special treatment. Oh, speaking of special treatment, if you do plan to sell, then be very careful not to knock them around too much
