Antique Chinese Metal and Carved Wood Nesting Bowls

Hello Community,

I just picked these up at an Estate Sale here in Palm Springs.
7 metal and carved wood Chinese Nesting Bowls.
Largest is 3 3/4" wide and 2 " tall
Smallest is 2" wide and 1 1/8" tall
Metal is Non-Magnetic

All intricately carved and metal appears to be hand hammered
I have found other similar Nesting Bowls ranging from 1200 a 1700 AD

Are these the real deal? Any Clue of their value?

Thanks in advance for any information!
