#877f variety of this note is not rare.
However, looking at yours again I believe in my rush and a small screen this morning I read the roman numerals in front of the serial incorrectly as only having 2. You have 3 roman numerals which should make this note 877a I think. My apologies for not seeing that earlier.
I see numerous raw (ungraded) 877a notes ranging in sold price from $61 TO $365. IS a note note to have in a collection
