C.B. here's some 'Heritage' background that may help (hopefully)
Original Heritage Series with dated & coin edged shields, fluted
bolsters, bone handles, and the 'Everlastingly Sharp' blade trade-
mark first issued in 1983 and ran thru 1986. Some other Heritage
marked knives were issued in later years but they differ from the
'83-'86 originals. Individual knives came in a hinged blue top box with
'Schrade's Heritage' and Ellenville, New York 12428 in gold lettering
on top. Boxes originally came with slip on white sleeve with pattern
# stamped on one end with black ink. Pattern #s unique to Heritage
like 2941-G for 285UH sized trapper in green bone. Heritage knives
available in green, red, or brown smooth bone. IIRC The Barlow was
replaced in 1985-86 with the 33 pattern jack knife.
As Orvet mentioned, sold prices in the 'Bay' best real time current price indicator.
If no sets like yours in there, research prices of individual Heritage knives
same year and color (if possible) My wild guess based on experience with
them several years ago would be $50/knife plus a little for the case assuming
all is like new with papers & box.
Hope this helps
