Ming Cup with some reign marks. Thank you for your help identifying it.
It is recommended to take this to an auction house or specialist on late Ming wares. A specific character of the Ming Jiaqing mark has the traits of an imperial mark. Photographs are insufficient for this, however detailed; the glaze and decoration need to be inspected close up to make sure. It might be an imperial item but only a hands-on inspection plus magnification of the glaze may help to make sure.
Thank you for your help. Really appreciated ! I'm trying now to to sort out some of the items first and do a mini-catalogue of them.
