My best guess:

59, 24, 56

Pic two, the pen cap is on butt of pen, so I have it pointed in opposite direction as other two pics, in case that's not obvious.

mirror: 29, 54, 26

If pic two shouldn't be switched, then: 59, 54, 56 or 29, 24, 26

Either way, 9, 4, 6

No idea what to make of any of it.
