1980 lake city nat match

I’ve recently acquired a box of lake city national match ammo. Box is unopened. Any ideas on the value ?

I guess my question is is it something to put away or something to shoot up during practice ?

Knowing the caliber and a photo or 2 of the box would be most helpful to answer your question. Is the box and ammo in “near perfect” condition, or has it been weathered, wet, or otherwise damaged?
