Need some more info on the items in the set, I am using Greenberg’s pocket price guide and it don’t list stuff as sets. Maybe the full size price guide lists sets but the pocket price guide don’t list sets.
Any way the 6167 red caboose is not worth that much, $9.00 if in excellant shape or $3.00 in good shape, the steam loco if the number is correct(1062) is worth between $12(good) & $27(excellant) and made in 1963 & 64, came with a 1062T tender. Also there are a few variations to the 6167 caboose, SP type, LL or UP, or painted or stamped, and these will also have an effect on its price. From what I can tell so far the set is from 1963 or 64.
Post War classification is limited to 1945-1969. Catalogued sets ran from #1000 thu around #13000.
The 1062 was only produced in 1963-1964. The slope back tender should be 1062T.
Here’s what I found in the sets.

Best guess as to date would be 1963, based on the possibility of you having the 6408 or the 6409-25 Flat, only produced in 1963. The Lehigh Hopper was not introduced until 1964…so it’s a bit of a head scratcher.
