Since when are plain steel implement seats worth $20 each?? Can't even begin to guess how many I used to see struggle to even bring $1, now that I would like to find a few they are bringing almost as much as cast iron ones. Actually, I picked up a couple cast seats today for less than what the steel ones were bringing? I would say that it was just a one time thing, but at the last 3 auctions I've gone to that had them, they have brought at least $10 each.
