Made between 1891-1900. These are used and discontinued pieces. Each piece is over 100 years old and has wear, especially on the trim. 
The photo in the picture may not be the one you receive as each piece is unique and hand-stamped, with hand painted gold trim. These pieces are not perfect, but there are no cracks, chips, or craze lines on any piece. 
This are a lovely piece of history to own or to complete your collection.
