I am relatively new to the microscopic world of Lincoln cents, but am enjoying learning about RPM's, etc. Here are a couple of photos of a 1957-D cent with what looks like a double-punched date. Both the 1 and the 5 seem to have a smaller digit atop a larger one, while the other digits look comparatively normal. Would the effect on the 1 and 5 be from punches of different depth? There is also something funky going on with the right side of the bow tie.
I can tell you for sure that dates have not been punched separately into dies since the early 1900s. So it's not an RPD. It's either die deterioration (VERY common in the 50s), doubled die, or machine doubling. I can't tell on my small screen, so I'll wait for someone else to post what they think.
That's right. The dates have been included on the Master Hub since 1909 so you can exclude a RPD. It appears to be machine doubling to me.
It looks quite different from any MD I have seen. Obviously, it cannot be an RPD. Any ideas about the bow tie?
