I submitted this coin to PCGS and it came back as not gradeable due to cracked planchet. I then submitted to NGC for grading and they called it reverse lamination. I have to say when I first notice the coin, I called it lamination but curious why PCGS would say cracked planchet... or can they be the same error?
A coin struck on a cracked planchet will have a very poor or absent ring. Most delamination error coins will ring, but at a higher pitch. Not sure what you'll get if you drop the slab on an anvil....

Interesting coin! Both lamination and cracked planchet errors refer to inherent flaws in the planchet prior to strike. The word "lamina" means a "thin layer of material" so a lamination error is typically when a thin layer of material is separating and the defect is primarily in the horizontal layer of the planchet. A cracked planchet is when the defect goes through the coin, being a vertical layer defect. Although it doesn't go entirely through the coin in this example, it looks to go somewhat deep, so it could possibly be called either but appears more like a vertical defect than a horizontal.
