Two antique chinese fire-gilt bronze wine cups

These little wine cups are made of gold gilt/fire gilt bronze.
Some pieces on the handles are broken/lost.
At the surface of the breaks, the colour of the bronze is black.
Otherwise it's hidden behind the gold surface.
The cups are handmade, with very, very small and fine details.
They show lots of ware, consistent with being at least about 150 years old.
But they could also be older than that.
All opinions/comments/thoughts are most appreciated!!
