Yes, I would say it definitely sells at a premium value, as most of the larger kits in this classic series do.
At least two have been sold through eBay auctions in the last year: one for $260 (~VF, Complete, #1765/5000) in March 2026, and the other for $407.78 (~FN/VF,
SW) in December 2025. Another one sold for a fixed price of $200 (~VF, Complete, #3510/5000) in March 2026.
Because yours is a sealed box, you can realistically expect it to command the higher end of that recent market range, as collectors heavily value intact original shrink wrap for these old Ral Partha sets.
