Hello, This is not a maker's mark in the sense you know it if from the west. This is a so-called period mark or reign mark stating the throne name of the emperor. With Chinese ceramics one cannot rely on the mark to judge age. It is the last thing we look at. The mark on your item says it was made during the reign of emperor Kangxi (1662-1722), however it is a faux mark. Kangxi marks were always blue and the type of character used here is also not from the Kangxi reign.
However, even with a faux mark antique Chinese porcelain may have its value...if it is not a modern item trying to look old, that is, IF it is antique! It is necessary to check the decoration, overall condition and age signs, and before all the bottom of ceramic items, to make sure.
The painting style of the partial enlarged picture looks promising, but more photos with better lighting (perhaps made outdoors) would be required to make sure.
If you wish, you can supply more pictures, or post pictures on the net and post the links here.
What would be required is a side view of the whole item, a view of its interior and the bottom and foot rim (very important) with good resolution.
