Prior to 1833, when Spode became known as Copeland and Garrett, Spode did not back stamp its pieces, only occasionally including a pattern number painted in red or impressed into the clay. Pieces dating from 1833 to 1847 include Copeland Garrett, impressed or printed, sometimes with late Spode or Spode.Continue Reading
A stamp or impression of Copeland or W.T. Copeland, sometimes combined with Spode, is found on pieces produced from 1847, when the Copeland family assumed full ownership of the company, until 1970. The month and year of production are stamped on the bottom of many flat pieces manufactured in the late 1800s to the early 1960s. Date stamps include a letter, signifying the month, over a two-digit number, representing the year. For example, M over 22 indicates production in March, 1922. First letters of each month indicate the month with the following exceptions: Y indicates May, U is June, L is July and T is August.
Back stamps from 1963 to 1976 include a series of letters indicating the year of production. The letters identifying the year differ depending on whether the piece is bone china, stone or earthenware. Simplified in 1976, the coding for year of production became A to N indicating 1976 to 1989; P to W, 1990 to 1997; and Y and Z for 1998 and1999. From 2000 until the end of production in 2009, the letter A plus a number indicates the year; A0 signifies production in 2000 and A2 for 2002.Learn more about Collecting
