Identification guide

Royal Copenhagen date marks

Royal Copenhagen date marks sit beside the three-wave factory device; shape and decoration numbers catalogue the product rather than its year.

Stroke position, waves and painter

Keep the stroke above or below the exact letter; its position is the date clue, not the painter initials. The three waves identify the factory tradition, while shape and decoration numbers catalogue the product. Compare the mark with the correct factory series.

Backstamp series to choose

Feature	Use
Early factory-stamp form	Compare 1870–1923 series
Later stamp and stroke position	Compare 1923 onward series
Painter initials	Identify painter, separate from year
Shape and decoration numbers	Identify product variant

What to check next

Photograph the full green stamp and blue waves without rotating away the stroke position. The factory’s series distinguishes 1870–1923 forms from the later 1923 onward overview. A model number is not a production year.
