2022 Scott Values For C13, C14, C15 Zeppelins?

I have personally bought the sold Zeps for over 50 years and they seem to be about the same relative price year after year. I remember taking a teaching job, a one night university class once a week, in order to buy my first set of mint never hinged zeps. About five years later I sold a set for the same amount of money I would be earning for teaching the same class… Five years later. Good thing I never hinge them though!

Siegel usually keeps the values updated here: https://siegelauctions.com/pse.php

Grade 80 should match the Scott catalog value.

Personally, I feel Zeppelins should be bought with certificates. Lots of re-perf's, re-gums, gum bends, creases, etc...

I've been happy to squeak by with a used set.

These are also some of the most graded stamps extant which is another way of trying to move an otherwise year over year static value. Funny thing is the graded values stagnated as well as the graded populations rapidly increased.
