Thank you for contacting Mearto.

I agree with you that it must be meant to read “famille verte” (green family), which is a type of Chinese porcelain whose palette is dominated by green, and usually has a lot of orange. Famille verte was commonly produced during the Kangxi era in China (1654-1722).

The double blue line with no characters in the middle on the bottom is also a hallmark of that era. It’s an unusual feature with an interesting back story (see below). The damage to one of the plates will negatively affect the price, but these are very valuable. I’ve included links to sales of similar plates below. There is a variance in prices, and part of that has to do with the reputation of the auction house. The Fair Market Value of the single unbroken plate is between $1800 and $2100. Collectors are interested in repaired plates, and these plates are historically valuable. Sold as a set, they could be worth slightly more.

About Kangxi era double blue line:

“There was a brief time during the Kangxi period in 1667 when the emperor issued an edict forbidding the use of his reign mark on porcelain in case the ceramics were smashed and discarded. This resulted in many porcelain marks simply comprising empty underglaze blue double circles.”
