Question; how many different releases of the 1967 Centuri catalog are their?

I have one that has glossy pages and one that has mat finished pages, and some of the pages have different pictures and prices? I would say the one with the glossy pages is from
early in the year and the other from the end of the year, because some of the prices are higher.
I don't know a lot about the variations of these Centuri catalogs , I am just glad to have these catalogs, as I sent for my very first catalog late in 1966 and the 1967 catalog was the very first one that I owned.
