Ok... value depends on if you are selling as 1 lot, individual or in mixed lots. If you sell them singular then check out multiple sold listings prices, take 10-20 identical auctions, total up the value divide by 10-20 (however many listings you use) to get an average or median #. That way you are in the middle ground and more likely to sell then asking extreme top dollar and sitting on them forever. I would sell the turtles as a set of 4, and either Rocksteady and Bebop as a set or add Krang and Shredder as a set of 4, April, and Splinter and Ace seperately.

I'd say sell in lots as if you sell singularly you will end up stuck with 1 turtle and april and maybe stuck with them for a while, where as a lot of people would want a full set of figures or st of good guys, bad guys etc.
Set of 4 turtles $100-150
4 bad guys $100-250
Ace $100 or so
April $40
Splinter $35-40, 50 if he has the felt head/squishy head.

Or ask $4-500 for the lot... that's my pricing on it. IMO. But factor in that the figures are being remade it will take away from the value over time. I'd invest in some plastic protective cases for them as anything that old has a tendency for the glue to let go from the cardboard backing. And don't punch out the unpunched holes, as the true MOC collector will pay extra.
