I recently bought some 25-21 Stevens brass for a super good deal with the intention on shooting it.   However after receiving them I realized it was a full box of factory original Winchester primed brass.   I was wondering if any body could put a rough price on them and also age.   I never could get the camera to focus on it but the headstamp is WRA co.

I'm a cartridge collector, but also a shooter of the old stuff.  The box in the Ward's Auction link (a good site) was for a SEALED box of 25-25 loaded cartridges.  SEALED boxes bring a big premium.  Boxes of 25-25 cartridges are much rarer than boxes of 25-21 New Primed Empties (NPEs).  Also, the tape on the box will drive down the collector value.

That said, how much would someone pay for a box of 25-21 NPEs?  $100?  They ain't makin' them anymore. 

Shuey's WRACo book says they never made many boxes between 1905 and 1915.  They dropped the odd stuff tooling up for WW1.  There is a date on the label.  That tells you when the label was approved.
