Rose Medallion Platter Help

I've had this platter for quite a few years, likely picked up at auction or a little shop somewhere; I honestly can't remember. Can anyone give me an estimate on the age of this? I'm looking to unload some stuff because I have way too much. However, I want to know what I have first before I start sending things off. Thank you for any help!

 

Chinese seal type mark - Dà qiánlóng qǐng - Qianlong Emperor Great Qing (dynasty). Probably third quarter of the 20th century, produced in Macau as well as the mainland, so a relatively modern reproduction.

 

Thank you!

 

They are certainly modern, it is interesting as I just watched video about famille rose by Chamberline and he notes that the ground was origionally orange and gradually as the plates become more modern the ground becomes a darker and more red colour.

 

Definitely interesting! I will say that the color that looks red in my photos (on my end anyway) is actually a burnt orange. I noticed it when I took the photos but wasn't able to correct it.
