KM's references an "inverted MF error". This is ambiguous
as it is unclear whether the error is
the inversion or the "MF".
All 1772 and
some 1773 Portrait 8 Reales
have inverted initials (KM
106.1).
The
"error" KM refers to is substituting "MF" for ""FM".
The
inversion may be a second "error", but this is the
style for all 1772 pieces.
These illustrations
should clarify.
