Hand painted plate

I’m not finding your plate but did find some with the same calligraphy and a blog that might interest you. I have no clue on value either 1stdibs has some going for $450, I’m assuming that’s
high. My search term was Turkish ceramic plate with Islamic calligraphy, I like image searches. Here’s the links https://ibnbattutatrail.wordpress.com/2013/06/25/blue-iznik-tiles-from-…

Hope someone else has better info for you.
