I made a more detailed mini for the duped Kabuto yesterday as i wanted to use it for something else. 169 should be fine. I'm posting what i had saved:

Mini for the Kabuto: This one requires a bit more digging, so i'm including a few sales.

=======> Sales (in order) for 150, 163, 169, 200(160), 200(?) 220. The sale for 220 should be capped at 200 given the B/Os for lower. That gives us a range of 150-200, with 175 being the mid-range.
