You need the Obverse to see this. There are a number of heavily repunched N's in Regina because the mint was re-using old 1876 single-serif N dies for '81 & a few '82's. The 1876 dies all had single serif N's, so every working die was hand-repunched to make them full-serif. As such, every re-used '76 die has repunches that sometime are extremely far off. We put one of them into the 2011 Charlton when we wrote it, but there are more than a few more. I think that some of the finished working dies were repunched by guys that had liquid lunches and were not seeing very well.
