The "B" Hornet will be variable based on just what it is. You see a lot of them NOT selling right now at the $1000 price point. The "A" variant is rarer but more exspensive and thus even a slower seller being a very specialized rifle.
A 257 Roberts in the "B" MIGHT bring $1000 but it would have be be a pretty early one with a red pad and a 3 screw trigger and really good wood. It is a fairly rare or uncommon rifle but prices are down on everything right now and there are 2 sitting on GB at the $1000/$1100 price point that haven't sold in over 3 months.
The asking price for the Lipskey "A" 257s in the Walnut/stainless seems to be $1200 or so right now. That being said again they aren't selling well at that price point.While most seem to eventually bring that, they often spend a very long time on the market before the guy that just has to have one shows up with the cash.
I own several 257 Roberts and I've seen them go for the $1000 price point but those had awfully good wood and were early or at least red pads.
Both the Hornet and the 257 Roberts are at least UNCOMMON rifles. That's a plus but it is also a minus. A plus because they are certainly more rare or uncommon than say a 30-06 or 243 or270 or a whole bunch of other #1s. The down side, is they aren't quite rare enough to truley attract the straight out collector with money to spend. As shooters, while great shooters and the Bob being one of the all time great deer rifles in my opinion, they are specialized rifles in the minds eye view of most shooters, especially younger guys and the lask of wide popularity tends to hold prices down.
We Official Old Farts seem to really like these two. Sadly for a seller most of us that are interested in these two calibers bought ours years ago and a guy can only rationalize so many before it gets silly.
A price point in the $750-$800 range is more likely to sell them and is fair unless the rifles are special in some way, especially in todays market.
Even at that price point I wouldn't look for them to be fast sellers simply because of low demand.
#1s seem to be slow across the board right now with a few exceptions.
