Hello, Can you post closeup pictures? These are too small to recognize any details. Or, even better would be if you could upload them to Photobucket or a similar site and post the links. Unfortunately, this blog has size limitations.
Good resolution is required. The pictures should incluce a picture of the whole bottom, including the foot rim and the mouth (just inside the top rim). A view the plum flower decoration in detail would also be of help.
The top mark looks genuine, the lower one could be spurious. But that does not mean your items necessarily are fake. During the late Qing dynasty a lot of items were made with Kangxi marks.
