I bought that in estate sale, i made some search here is a link for the same thing, thanks.
Dates late 1960's. There are several on "buy it now" on ebay...priced about $50 give or take a few.
Hard to say what it's "worth"...because these are items for sale that no one has bought.
Frankly If I saw that at a sale for $50 I believe I would buy it....but if I had to pay shipping on eBay....probably not.
Here is a link that might be useful: Tureen
I did very well then, I bought it less than $5, really like it,
