I've had to pay a premium versus pre-Covid prices even for non-pedigree books (with the exception of some low-grade filler copies that I've picked up.)
I picked up this 9.4 copy of Planet 39 for $4,800 (which I considered a very high price) right before COVID hit; the 9.2 Promise copy just sold for $8,400. I'm not sure how much of that is due to the hype around the promise collection and how much is due to inflation.
ETA: The price on the Rangers 49 doesn't surprise me, but even with the current market, I would have expected the Wings 102 to stay under $200.
