chriseug New Member United States 10 Posts	Posted 10/06/2020 01:42 am Hi- ran across this coin because of the notch, then noticed the high bump on the D that looked like doubling. Closer inspection shows the following. Thoughts? Looks different than the two on variety vista if it's actually a DDO, and all the others on here don't have this kind of definition. (Also, any feedback on a notch like this is appreciated.) Thanks & Edited by chriseug 10/06/2020 02:22 am Report this Post to the Staff

spru Bedrock of the Community United States 12477 Posts	Posted 10/06/2020 01:56 am It looks like what is called "split plate doubling", which is not really an error. The copper plating splits during the strike and exposes some of the zinc core. This can lead to corrosion and bubbling around the splits, which can look like doubling because of the way it follows the letters/numbers.

chriseug New Member United States 10 Posts	Posted 10/06/2020 02:28 am Thanks- I looked into several split plate/stretching examples. Just in case, I added one more image, almost looks like a D struck on top of a 45 degree S, but I assume that just wouldn't happen (?) Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 10/06/2020 08:50 am Also DDD on the last '8'. When the zinc is exposed, the clock is already ticking the countdown for the life of this coin. Report this Post to the Staff

ijn1944 Bedrock of the Community United States 19402 Posts	Posted 10/06/2020 12:47 pm Split plate doubling, and emerging zinc rot in the immediate vicinity of the mint mark may suggest a 'S', but that's not a legit S mint mark. Report this Post to the Staff
