These issues of stamps were issued in 1973. For your records, the Scott catalouge numbers for the issue is either 1500, 1501, 1502 or C86. Each stamp is different and unsure which one you have as they are all the same topic.
Although, neither of these stamps are really worth much to tell you the truth. They are listed with the minimum value in Scott ($0.20) for either mint or used. If they are unused, I would recommend them to be used on your mail. The stamps wouldn't be worth much more than their face value.
