I work for a nonprofit and we were given a Porcelain Chinese Famille Rose Medallion fish bowl Koi planter. It does have the red stamp on the bottom of the planter. No stand.
I have been searching for a few days with no luck on its value. Could you provide a price, therefore, we could try to sell it?

You should be able to look through these to get an idea of price !! You can also look on ebay and check the sold prices to see what people are actually paying for similar planters !!
I added original pics.
