Literature: Kopicki (2007) does not describe, Nechitaylo, Ermachenko, and Zamekhovski (2018) do not note such a punctuation of errors,
although they have cataloged many other punctuations of incorrect inscriptions.
A very interesting sixpence with a punctuation error in the obverse legend - it was probably PLO, then corrected to POL.
As a result, it came out as if PDD with the second D reversed.
An attractive piece with a beautiful mirror. Slightly deficient. Light soiling and patina on the rim.
It definitely makes a better impression in person.
