But the area on the roof is not seen as often as it was noticed on the wheat cents. The wheat cents were run way past the normal retirement. Thus the weird stuff we see on these coins. This Memorial cent is getting closer to normal retirement. A event just hasn't forced the retirement yet. But soon. No premium for these, just an extended life for this die.
