Antique Painted Blue Flower Goldleaf Vase with Handles Unknown Hallmark

I got this antique vase from my grandmother and I would love to know more about it. I am not sure if it is from England but I would think it is from the 19th century. There is a hallmark on the bottom but I am not able to find out who made this piece. Along with the blue hallmark, the bottom has the marks "9XF" and "14" pressed into the bottom. The vase is about a foot tall and doesn't have any chips or cracks. If anyone could please help me out with some information; porcelain? maker? age? origin? value? period? type of pottery? style? etc. Thank you very much for your input and I am excited to learn more.
