M28a2 munitions crate?

recently i found an old wooden munitions crate. not sure how old but it is wooden and says it held 3 m28a2 heat rockets. ive done some searching so i know what the m28a2 rockets were for, i'm not looking for a history lesson. i am wondering if they are worth anything? i would like to keep it to use for holding my many different ammo boxes, but could always use a little extra money. if anybody knows anything please let me know, i have already checked ebay and a couple other sites.
