[size=12]I was to an auction today below Lancaster, PA, that had a pretty good amount of cast iron at it. Very little of it was unmarked, and over half was Griswold. Honestly, most of the pieces were pretty common -- LBL smooth bottom or small logo skillets -- but there were a few pieces that were a bit less common. I don't think anything there had a blue book value over $150, and like I say, a lot of them were the sort of pans where there's a thousand out there for everyone who wants one. In general, the quality was OK, but here and there a badly pitted griddle could be found, and several of the pieces needed cleaning. The auctioneers were... disorganized... and I won't say any more about that here.
I came away with only one piece, and that was just an unmarked 755 skillet. Most of the time, I couldn't even get a bid in on any pieces that I would have liked to have taken home before they were so far above their listed value that I wasn't interested anymore. I did a little quick scratchwork when I got home, and quite a few of the pieces were bringing 1.5 or 1.9 times their listed blue book value (using the high end of any value ranges, and according to the fifth edition of the blue book.) Two 746 no. 9 long griddles brought 2.1 and 2.3 times their listed value, and they both needed cleaning. Very, very few things went for less than their listed value, and if they did then it was usually due to pitting or some other obvious flaw. But even some fairly badly pitted pieces were commanding 1.7 or 1.9 times their list price.
Last September, not quite a year ago, I was to a different sale out west of State College. Stuff better than this was going for giveaway prices compared to blue book, and it was being sold by a much better auctioneer (in my opinion.) I don't know what to blame it on -- geography, economy, or e-bay -- but now I'd have to grudgingly agree with what Janis said. When small logo Griswold brings almost twice what it's worth, consistently, all day long, then prices really are at the crazy high point.
But, again, at least the stuff I already own is maintaining value.[/size]
