But this date clearly didn't enter circulation. Perhaps the term business strike is a better one. In other words coins struck in quantity for circuation, not struck for testing or trial purposes that never got to mass production. For the same reason, I don't regard the 1945 silver threepence to be something I would collect, nor the Edward VIII coins of 1936. As much as anything my lack of interest stems from the lack of material, plus the lack of funds on the scale needed to buy them. For me all these kinds of coins are interesting curiosities that help define the history of numismatics and the nation, but nothing more.
