IMHO, these are more common books, but if they are 9.0 or better, they would likely be worth grading. Most would only have a handful of graded copies currently... having said that, thye could take awhile to sell, as the pool of Whitman collectors, while growing, is still relatively small.
if you do get them graded, I would be happy to make an offer on some. I have one of these in 9.2 and two others in 9.6, and in all 3 instances, they are either CGC highest or 2nd highest. Having said that, there's a 9.8 of one of these B&B issues that has gone unsold on eBay for some time at about $175, so - for these particular books - I think the ceiling is still a little lower than that.
Hope that helps...
