I think this is a mid 20th or possibly later copy of a c1900 vase. A period one would fetch about $700-$1000 but the detail on this isn't quite right
Chenghua mark but later. Chenghua " reproductions " were commonly produced during the late 19th, early 20th.
I've been discussing these marks with other experts recently, including those with identification websites, and it's thought that many items catalogued several decades ago as Ming dynasty were in fact late 19th century. The internet has brought together collectors and historians and helped rewrite the guide books in some instances.
Some still makes mistakes and date things by the mark only but you will find many auction houses now not trying to be too specific and just describing the mark.
