A very attractive Old Sheffield Plate Wine Coaster. One of the attributes that this piece has is a wonderful patina. As Old Sheffield Plate (see heading at the top of Old Sheffield Plate regarding this technique) is a hand fused process, there is copper wearing through on some points (known as bleeding) which is quite attractive to the naked eye. This 19th century Old Sheffield Plate Wine Coaster has a decorative border, a mahogany base and a new green felt bottom to protect the table.
