I think your mailbox is going to fill up pretty fast. I just answered another posters inquiry on value of his 629-4 in a similar configuration.
Yours is more desirable; if my eyes aren't deceiving me you have a longer ejector rod than is usually found on the 3 inchers. These are a bit harder to find, and although the market is down from highs in the last couple of years, I wouldn't be surprised if you saw offers in the high 3 figures, maybe even more.
You can go to the auction sites and search completed auctions, that can be a good indicator of true value on the open market.
Nice gun, I'm tempted to shoot you a pm myself
