Though the majority of all known "one cut corner" plaques are upper (no matter the construction); very few are seen where the cut is on the bottom.

I would be interested in seeing any others such as seen below, even if from a manufacturer's catalog... or, better yet, another denomination from this series.


Interesting thing about this piece; it was listed on eBay for over 8 months before I stumbled upon it and, that was due to a spelling error or mine...
