I am thinking fake. The dragon looks Ok to me for early Qing, maybe it should be a bit more fierce. But the plate feels somehow cheap to touch, a bit lighter and the inside of the foot rim is slanted outwards. The double circles look suspicious to me as well (like too dark). Plus, no significant age signs.
What do you think?
Thanks
You got it. But my personal opinion is that the dragon looks too tame, more like a prawn, because it is later (20th century). Yes, the ring mark has a different color and looks more as if it were printed, but the foot rim is also 20th century.
FYI, plates with the 'dragon over the wall' decoration usually do not have that much white, empty space, and in many cases the dragon has a more three-dimensional appearance. There is an example of a small dish in the gallery.
