Lookup table of hat prices by decade?

Frequently here I see people mention that a certain original price on a vintage hat dates the hat to the 1930s or whatever. I'm curious too, as I've just bought a very nice fedora which the seller said was 1950s, and which has a price tag on $7.50 on it. Is there a lookup table, here or elsewhere, rough or not, with hat prices by decade?

Oh, I know each manufacturer had a range of prices, from entry level hat to finest quality, as we have with cars today. But say you've got a mid-level hat. Is there a resource where, if you know the price, you can get an idea of its age? Or is that knowledge something you expert collectors have gleaned over the years?

I think everyone was getting prices from the old hat ads that have been posted. And they've been posted all over the place on the Lounge. There are a bunch of Stetson ones, but other makers as well. They aren't centrally located as far as I know, though.
