ID help of Celadon plate with clear marking

[RobS]

I'm seeking identification help for a Celadon plate that I believe would be classified as famille rose with flowers birds, and butterflies. I found a similar marking from the Qing Tongzhi period. My question is does this piece appear to possibly be this old or is it a later 20th century copy. Any opinions will be greatly appreciated.
