Antique fish mark bowl

[Turriya lwin]

One of my relative found this bowl, has a fish figure within the bowl, it's not painted
You can see the picture of the item in the attached file below. Please help me identify the age of this bowl and possible price of it. Many of the antique collectors are interested in it so I want to know the real value.

Without detailed pictures of bottom, foot rim and interior it is difficult to tell more.  However, the style of this celadon decoration looks as if it was from a more recent time.
