Sounds like some shopkeepers did accept these crown pieces but they had to take them to the bank afterwards. Hence, they were "money" in a sense but I wouldn't say they have "circulated" in the 70s.
In a way that doesn't matter. Looking at the 1982 prices gives you some idea of the relative scarcity, and you can then use the current values of the standard issue to calculate the value of the scarcer variety; possibly adding a slight premium to allow for the greater modern interest in rare varieties.
