I see this as a RPD. But not sure if that's the cause because I don't know the production method for BC coins from the 40's. Anyway, look at the "3" in the date. Common? Unusual? Value? (I get the impression that except for US and maybe Canadian collectors errors of this type are only mildly interesting.) I also have two 1945 dated SA 3d coins with the same but lesser characteristics. Are they worth listing?
