A boxed 5906, VBK9296, described as ANIB sold for $725, Lot 505, Milestone Auctions in Ohio, June 27. Plus a 20% buyers premium (crosslisted on invaluable-dot-com)

A pair sold for $950 (+20% premium), described as with edge wear and agency logos, June 13, Lot 2492 Poulin Antiques.

Shipping and FFL fees come on top of that.

Not saying that is typical, because low prices seemed to start around $325. However, as-new or unfired S&W handguns, revolver or semi auto, have been selling for eye popping prices at auction.

In other words, I think @prochi2K did just fine.
