Hi, basically, we do not talk about values here, because these are dependent on too many factors. You can consult valuemystuff.com, which seems to pretty low cost.
The pictures are too small to see anything clearly, but you seem to have a famille rose set. These are probably still being made and those made later in the 20th century have hardly collecting value. So price is dependent on whether the set is antique. The Qianlong mark is spurious, probably. Most of these were made for export and did not have marks, or English marks (CHINA, or Made in China), from late Qing dynasty to early republic.
