identifying 2 bowls

[ginnyclark]

I'm not a collector?just interested in knowing if these bowls should be given to Goodwill...or kept or sold?  I hope the photos are sufficient for someone to give me some information about these. I was told a few years ago that they are marked Ch'ien Lung (1736-1795). But someone then said they are a later copy.
The marks on the bottom of both are the same. I've attached a photo of that.
Both are 10" in diameter.

Thanks for whatever information you can give me!

This type of base appears mainly on 20th century items.
