It is worth what 30 year old used ammunition is worth (less than retail, but more than you father paid for it).
I don't think it has "collector" value to anyone if that is what you are asking, but I could be wrong and you get what someone deems it to be worth.
It used to be on the shelf in every small town Co-Op on the Prairies, and likely still sitting in glove boxes of old farm trucks and dresser drawers of old farmers throughout the countryside.
It went bang most of the time back then, and don't doubt it still will today.
That being said, modern .22 ammunition has actually progressed a fair bit since they were made, and if you are using it for anything other than plinking (like hunting small game), there are much better rounds on the market (if you find it on the shelf).
