Hello, Guan Yin Mirror Image Statues

Hello everyone, i’m ashley and i am an antique newbie. Can someone help me value these? Background: bought off facebook for 25 for both. They’re very tall and heavy. No marks on the bottoms. The lady i got them from knows nothing. Values on google are all over the map! How do i properly value these?
There’s a long crack on the back of one and one of the detachable hands is broken. Otherwise immaculate.

 

Very pretty,but can we see the bottom? Knee jerk is newish but that could be 40-50 years ago newish.
