7.92X33mm Kurz ammo isn't difficult to come by, lots of online folks selling current mfgr boxes of 20 for $17.
If you're asking about collector types, you need to come up with a pile more info. What condition are they in? We talking "pretty good I think" or NRA 80%?
Headstamp is where the real differences are, naturally the early years are the more difficult to come by, and which mfgr and sub codes.
Then your answer becomes, it's worth what someone is willing to pay for it, but am auction site is a pretty good judge of what things actually sell for.
