I'm going to buck the majority, who seem to be gauging on yard sale prices. They have to clean up well, but if they do, I'd say piecing out on eBay about $30-$40 for the lot. You may have to sit on them for awhile until you find the person looking for that particular brand and size. Always a market for Craftsman USA--hell, on a good day you can sell pictures of them. If someone needs that speed handle to complete an old Walden set, that's a 10-spot right there--again, sitting on it for who knows how long until the right buyer comes along. That 3/8 x 7/16 blackhawk dbe is a long pattern--it's longer than the 5/8 above it, and it's a blackhawk. the 1/2" Craftsman isn't too bad and is a pointed-A =V=, pre-1968. The powrkraft is a scoop-type Barcalo--Barcalo sells. Original Williams superrech sell well too, especially since they tend to be a little longer than most standard combos--if they clean up well, that 1/2 and 9/16 as a pair (most popular SAE sizes there are) are an easy $8 plus shipping. I'd like to see the other side of the Cman ratcheting box wrench--depending on what it is, there's folks who want them too.
But....there is no BIG money here, and you'll have to work at it. I know everyone's looking for the $1 snap-on ratchet they can glean from granny's yard sale and flip it for $75. Nothing like that here. I sell $5-$10 wrenches all the time, so I'm used to the small-potato sales. It's a hobby for me--trust me, the lot is worth more than $0 to $10.
