The "Made in England" stamp began appearing on some Wedgwood china pieces in 1898. In 1908 the stamp replaced the updated Wedgwood mark that had featured the word "England" for general use.
In 1860 the Wedgwood factory began marking their wares with a three-letter code to indicate the date of the piece's manufacture. The first letter stood for the month it was manufactured, while the second letter indicated the potter who threw the shape for the piece. The last letter showed the year that the piece was made, starting with the letter "O" to represent the year 1860. The word "England" was added to the letters in 1891 and remained until 1906, when numbers replaced the letters representing the month the pieces were made.
