Remember this date is just when the design was registered.You decide if they are genuine and if you would pay the price.We get a lot of questions about Nippon backstamps and dates of manufacture. (Note: the left bottom side of the Torri mark is slightly worn, it should be even with the right bottom side of the mark.) “Pagoda Hand Painted Nippon”, no known manufacturing date(s). “Imperial Nippon”, found in blue (shown) and green.
From 1783 onwards the year mark was impressed alongside the factory mark.The Public Record office and the British Government tend to enforce these marks and registration numbers.Companies located outside the UK who have reproduced items, and tried to use a facsimile of the marks or numbering system have been sued, and have had sanctions imposed against them.If you know any dates for a backstamp not shown here, feel free to leave the information in the comments. UPDATE 1/4/12: We’ve added more backstamps to this post! The script used in “Hand Painted” is also a bit different. UPDATE 2/20/12: Even more backstamps have been added to the list!
