It depends if the disc if first or second pressing, you didn't specify.
If it's the second option (most common), I'd say you could get 100 + 100 € as a maximum if both pieces were tested and 100% working. Since this is not the case, expect a price drop of 30-40 % per piece. Usually those discs do not tend to rot if stored properly. Different story for the pcb. I've seen faulty ones and in some cases they are not a easy fix given the presence of some rare and hard to replace SMD ICs.
Good luck,
