Nothing unusual about this one, but I would definitely check out gunbroker for recent "completed auctions" to see recent selling prices -- it's probably higher than most people assume.
I know because I bought some of the 81 surplus imports that came in a couple years ago -- it was a great deal, at the time. So just recently, I noted that RGUNS was still posting surplus model 81's and 82's to gunbroker, and I was thinking of taking a shot somewhere around the $300 level. HA! No such luck. That ship has apparently sailed -- even the pretty dinged-up ones went for over $500, and nice-looking ones (still surplus pistols we're talking about) currently have bids north of $750.
Looks like commercial 85's go for at least as much. It's easy to see completed auctions well north of $1k when condition approaches LNIB.
It's an interesting phenomenon to watch. In a world filled with perfectly serviceable plastic pistols, craftsmanship commands a premium, even if it's a 30 years old used .32acp that sold for less than $300 on the surplus market, not long ago.
