1937 Nickel With Doubling

I believe that is Machine Doubling. Very cool find, but not worth a premium.

Thanks for your thoughts. How does the 9 and 3 show doubling and not the other numbers?

Definitely Machine Doubling, no question about it.

The exact story as to how certain parts of the coin can show the doubling and other parts don't compares to how you can stand with a couple of friends outside on a windy day, and the one facing against the wind will always think it's windier than the others, because they aren't facing the wind.

The devices that are in the right place on the coin and whose sides are facing the direction of the pressure will take the brunt of the damage when the coin is popped off the die and shelf doubled. My best guess is that the 9 and 3 caught it because the 1 and 7 face different angles, are in somewhat different parts of the design, and popped out of the die more easily than the 9 and 3.

Another interesting tidbit in this area is the mintmark on Washington silver quarters and how it can be doubled by force of ejection while no other areas are. These are VERY commonly mistaken as RPMs, and aren't. The reason this occurs is simple. The mintmark was the only part of the quarter reverse that was added to the die by hand, and wasn't always punched in with the correct depth or angle to create the perfectly beveled edges necessary to assist with cleanly ejecting the coins from the die. All the rest of the design is shallow, has no harshly angled surfaces, and usually slides off the die like a hot knife through butter. The one sticking point is usually the mintmark, thus the only point that suffers from Machine Doubling on occasion.
