No, not really. It is a nice addition when they do have them though. Ones that can be traced to a more famous unit can command higher prices (just like in any collectibles).
Mine is attributed to a signal school (marked on scabbard throat, crossguard and back of hanger. The shoulder boards are for the unit.]
The other one is not marked to a unit.
Both have the WAA so that means they were unit property and most likely issued when an NCO needed a sword for ceremonial purposes.
