Description

VINTAGE Hallmarked SILVER PLATE WINE CHAMPAGNE BOTTLE COASTER FORMICA BASE Tray
Mid-century modern pierced silver-plate and Formica Wine or Champagne Bottle coaster tray, 3 ball feet,
Castle W Crown mark. I assume this is silver-plate as there is no Sterling mark on it. However, it does have a mark that I can not trace down: a castle tower made of bricks inside a shield, a stylized W that looks like a trident also inside a shield, and then a crown, again on a shield. The center is a wood tone Formica that withstands just about anything - though it does show some signs of use. I found the same listing with this sticker (BUT It is not on this one)  The silver-plate is in great condition. Very attractive.
It measures 6 1/4" diameter and is 1 1/2" high
Lovely silver ball feet
