GD165623,
Are these once fired empties, or are they new "brass" sold for reloaders?
I think the value would depend, in the case of once fired brass I'd think very little value, on par with other once fired cases.
If they are new brass cases that S&W sold to reloaders, that would bring a slight premium, certainly for a S&W collector.
Can't advise on actual values, these don't show up often.
Can you describe the box they are in?
If new unprimed cases, are they nickel or brass?
Here's a pic of some S&W (Fiocchi) new unprimed cases I found a couple years back, the first I've run across, for comparison.
I'd be interested in a couple/few boxes if these are new unprimed cases, similar to the above pic.
Regards,
