Hey, Sgt Hoss!!!! Welcome.
To all and sundry, Scot here is the KING OF DARE DEVIL COLLECTORS. Just as the rest of us might pick up an extra loaf of bread at the grocery story on the way home, Scot completes Dare Devil sets!
Scot, you pose an interesting question and I would initially hesitate to venture a guess. Here's why:
A graded Dare Devils set should usually command serious value. And most everything on Mastro, etc., does tend to sell for a multiple of what one would expect, anyway (God bless 'em!). So all this works in your favor of getting a great price on a scarce set. But offsetting all that is the fact that many of the cards are lower grade, so overall the set may not attract a premium price, typically driven by 'slabbed' collectors seeking cards high in the registry hierarchy.
You might check that website that has the database from all the major auction houses, and see how past sets went?
