Help identifying mark & era

by Sage
(California)

Need help, please! I am in the early stages of learning about Chinese porcelain/pottery, and this one is out of my range.

This mark is from a plate. I think I have identified the mark as being Chenghua (1465-1487). The plate is certainly an antique, but I seriously doubt it is as antique as it's mark seems to claim it is. (But I'm fairly new to this & could be misreading the mark completely).

Any help confirming what the mark says would be so *much* appreciated; as would any help in what to look for to verify or identify when the plate was really made.

peace & thanks!!
