I just acquired this piece and the autograph has changed many times! How do I date this piece? Thank you for your help. I am assuming the older the piece the more valuable
It doesnāt necessarily follow that the older the piece, the more value it has since there will be numerous exceptions to that, depending on the rarity of the pattern and decorative appeal. As patterns go, yours doesnāt have exceptional appeal, nice though it is.
That style of mark in script lettering with the swirl running from the ārā of āMoserā to the letter āKā of the factory location first saw use around 1911, with the location as āKarlsbadā in German. After WWII, the mark changed to the Czech name of āKarlovy Varyā and has been used ever since (along with other styles of mark).
