Nine Valley Kutani Cup

I have a cup that is a 'Nine Valley' Kutani piece. It only has the brush stroke marks underneath that represents 'Nine' (this one looks like an incursive 'r') and the one underneath that is the mark that represents 'Valley' (this one looks like a pagoda house). Theyre both in red. The cup is white porcelain with 3 chinese figures on it....2 men and 1 woman. It also has verticle chinese wrtiting on it that looks kinda arabic-ish. The colors on the cup consist of brown, black, gold, turquoise dots,black or brown swirls, a little bit of red and a little bit of purple. Does anyone have any idea or thoughts about how old this is and what it may be worth?
