No, the most boring by far concerns the 1937 penny reverse. There's two MICRO-MICRO varieties, which have something to do with whether the exergue line crosses through a tooth or not. Both are equally common, and I've never even looked to see which mine is, or the proof, as I JUST DON'T CARE I not heard of the exergue example. The pointing of the P in PENNY is the usual way, P to tooth and P to gap. There's two obverse as well.
