You have JABO Classics. 30 25# boxes is a nice amount. You probably have 5/8" boxes, 3/4" boxes, and 7/8"-1" range cases, but it is possible you have 1/2" peewee cases too. If you take an in focus photo of each box I could probably date each one for you if interested. If you were to sell them by the case, you might expect to get $50-$250 per each box. You could spend the rest of your life selling them 1 by 1 and get a lot more money (and spend A LOT more time doing it). Would love to see clear photos of each box and I would most likely be interested in several.
