IIRC I've seen full "military" sets go for over $300.00, but the higher priced ones were the full set including the SS EOD heads and the large pouch (these weren't available separately and so are MUCH harder to find, unlike the cable cutters, tech/fisherman, regular needlenose and blunt nose plier heads which you could buy as accessories/spares).
Many collectors are after a full set, not an incomplete grouping. You may get more interest on ebay if you split that group into two lots with one handle in each, and no duplicate plier heads.
