Wow! It may be in the
Cud Book, which I have a copy, only it's in storage - and I'm not sure what box it's in. So I can't help by looking it up. There are some really large
Cuds on
Shield nickels in that book. This one is a doozy! Also just because it's not listed at cuds-on-coins or in any of the big books certainly doesn't mean it's not known, there are a lot of lesser known
Cud errors around. This one is sure a major one though. Very impressive.
