Japanese Urn

My mother, grandmother, and I found it in a Goodwill store. I absolutely loved it! It seems that someone else was trying to sell it before being donated to Goodwill. It had a price tag of $35.00 on it from a different store. (Perhaps the kind of self-made price tag you would find on an item in an antique or second-hand store.) Goodwill had their price tag on it for $15.00. After checking it over, being amazed at the excellent condition it was in, and finding the legit markings on the bottom of this piece, we thought it would be a good buy and my grandmother bought it for me. I have researched it a little further online and only found information on the company stamp and sticker on the bottom. I know some of these pieces can be quite valuable depending on who made them and when. I was wondering if I have a nice little piece of history for the right price. Whatever the outcome of the value, I will cherish this work of art for many years to come!
