Nice find!
Haven't seen many sell recently. A RL Calibur is 10-12 right now (50h and two 50s). A 2-attribute 70 hit went for 90+ pretty quickly the other day.
People tend to prefer a DF set with 1 N/AB and 1 M/D, so AB/D isn't super desirable. But it is two healthy attribute amounts plus 60H, so there's a lot of value regardless.
I could see it landing around 35+. There should be a healthy demand for good PGF food so if I were you I would set a reasonable reserve and allow the bidding wars to commence. Best of luck.
