IME, there is no definitive pricing for Playboys. The range is so unpredictable that it's a matter of a price finding a buyer that is willing to pay it.
I've seen issues from the '50s through current selling for pennies, and I've seen them sell for dollars.
IMO, it's a buyers market *IF* you're patient. Aside from the first two or three years, you can put a full run together on the cheap. You just have to be patient.
Good luck if you're selling. If you're in a hurry for the money, you'll get almost nothing for them. If you're not in a hurry, you'll be years selling a few issues at a time.
