Ok, that was my first thought. In California older Drivers Licenses were sent out stapled to a piece of paper. When forgers (drinking age) tried to copy them they usually screwed up and had two black dots for the staple but no holes...I was unaware of straight pins maybe by 1964 they got staples? I would like to measure them but would need to know the paper size so if anyone has their BC let us know size !
