This tutorial is going to be talking about Split Plate Doubling in depth, and how it happens. Here we go. Ever since the U.S. Mint switched over to Copper plated zinc planchets, this common awful problem started to happen a lot. Sometimes when the Copper plated zinc planchets are struck, the thin Copper plating overstretches and causes the thin plating to split, exposing the underlying zinc core (the shiny silver areas). Because of this issue happening, zinc rot can occur and eat away at the zinc core, if the coin is exposed to the air in the environment long enough. This issue unfortunately causes a lot of the newer Lincoln Cents to get destroyed. Anyways, let's get back to my tutorial. Common areas to see Split Plate Doubling is the motto, "LIBERTY", profile, and the date on the obverse. On the reverse, the most common areas to see this, is "OF AMERICA", the left and right areas of the memorial bays, and the "FG" initials. This seems to happen a lot on the Off Center struck Lincoln Cents and Broadstruck Cents. Anyways, I hope this helps. Tell me what you think everybody. Did I do a good job explaining this, or does it need improvement?

You're very welcome CoinTheTerm and thank you for commenting! I appreciate it! Just wanted to do a quick, but thorough tutorial, since it's been a while since I made one. I will continue to make more tutorials in the future.
