It's from the early to mid 70's. That manufacturer made them for Sk, mac, and a few others too.
How much is different for different folks. I wouldn't pay more than a hundred bucks for the set.
That doesn't mean I don't think it's really cool though.
Mind saying when or where the auction the is. I live in southern pa too. I don't want to compete with you on the box but maybe they got other good stuff.
