Not sure what the definition of (Clearly in your world is)I see 191-not completely identifiable but whatever you think.
I was trying to tell if the first Lincoln with the "S" was a 1918 or 1919 but I couldn't tell if there was a VDB. But if you could tell ? you could separate the 2 types of Lincolns 1910-1917 and 1918-1919
I'll be home this weekend so I'll have a chance to pull out some of my similar Lincolns that I've found looking through bulk Wheat Cents last summer. True lowballs in the Lincoln Cent series are very rare, most likely because the last date digit is so close to the rim. PCGS has only graded four PO-01s and twelve FR-02s. Even the top lowball set on the PCGS registry has the Wheat in AG-03. I might have one somewhere that could make FR-02 with the wheat ears fully merged into the rim, but I'd have to check.
