That fella is a dreamer. His empty boxes are priced 5x what they sell for regularly on Ebay. I rarely see full, one piece Monark or HiPower boxes sell for more than $75. The Red Sweater boxes bring up to maybe $125 for the sub gauges. The highest selling price I've ever seen for a full, one piece Federal was $150 for 16ga Skeet and Trap loads.....then a fella found a full case and flooded the market with minty ones for $60.

If yours is 99%, it should sell for $50-75.
