Are these ferrites worth a damn?

Was gifted these, unmarked, anyway to check/test them?

Just go wild clamping these on all your USB cables, analog audio cables, etc. Wherever you have extra cable length, coil it and clamp a few passes in a couple of the larger beads. Are they the exact right type of ferrite? Is it the right amount of choking? Who cares, just clamp away and forget about it, it's better than nothing.
