depends on the prefix to collectors, but I'm guess it is gun-only? so not really a collectible if so.
I passed on a fired GB/LE in VG but not excellent condition for <900 last season. Thats JMHO.
For quick visual reference, the gas block must have the sling loop on the side, the folder must have the correct "latching bumper" and the bayonet lug/sight and muzzle brake must be original. Ruger will letter the as-shipped condition by s/n.
I'm no expert. Lots of fakes appeared out there when Ruger ceased citizen sales.
