Hi Don,
That’s perfectly fair. I’ll mention that the only place I’ve been able to find that has a tool to help with this kind of thing is brickpicker.com (http://www.brickpicker.com/bpms/lego_lot_price_calculator.cfm). The “used” value for everything is about $8860 the last time I checked and that’s not accounting for the sets I don’t have instructions for or any of the minifigs. If I had to throw out a number, I’d say $5500 for the whole thing seems reasonable.
Between the fantasy-era warship, the 1989 pirate boat, the Queen Anne, and maybe something else floating around in there, I have a lot of the larger boat pieces if that’s something you’re interested in. I also have 2 giant sharks (among lots of other animals) from one of the Agents sets on the list that are pretty fantastic.
