These are the single squeeze dies and the Doubled Dies are located in the center of the design, not on that area of the coins. These devices are incuse, on the coin (raised on the die) so the slightest movement of the dies will cause the MD on the devices. I surveyed 100 of these coins and I noticed 70% had slight/medium/strong
Machine Doubling on these devices on that outer ring area. None of these will be a doubled die. Check the sites to see what you should be looking for on the doubled dies. You might be surprised at what you are missing?
