As pointed out already, it probably can't hurt to start at $1000 (unless some potential buyers balk at that price and disappear).
But, I see these come up for sale periodically on the statewide classfied sites, and in my opinion, $1000 is highly optimistic.
If you don't mind letting it sit for a year, then give it a shot, but if you're looking to get some cash out of it anytime soon, I'd at least post it down at $900, a number that doesn't have the same intimidating quality that $1000 does !!

But, even then, I would expect to see this get re-posted quite a few times at $900, and possibly even down at $800.
You gotta keep in mind, you're competing in a fairly flooded and depressed 1911 used market, too.
But, this is all based on my personal impressions from regularly scanning the classified sites here in Georgia, different areas of the country often have widely varying demand and prices on certain guns, so who knows. All it takes is that
one guy !
