An archaic or rare word referring to a small groat (a coin), or a term of unknown or highly regional meaning.
Possibly a diminutive of groat (an old English silver coin worth four pennies), with the -et suffix suggesting smallness, though historical documentation is sparse.
This might be one of English's ghost words—terms so rare they appear in only one old manuscript and nobody's sure what they actually meant or if they were spelling errors.
