Hay bigblock, Ive grown up around hunting and fishing and my father collects old shotgun shell boxes and decoys, We have a few DU items ourselves, I called my father on this since he has been collecting them since I was a child, He said he would say they are worth anywhere from $25 to $30 for the box, They are most likley plastic shells and you can still buy paper shotgun shells in the original box for around 25 and higher, DU on them does make them worth this because he said he has never seen any like this before, I would put it away for safe keeping or try E-bay to sell, I would also put plastic wrap around the box like seran wrap to preserve and protect the outside of the box. Hope this helps you friend. Firedog
