Paulo,
Here in the US, we call this a demijohn or sometimes a carboy. It is a generic term for a large storage bottle. It is entirely possible that someone used it in which to make wine.
To my eye, this bottle is of European manufacture.
Judging from your IP address, you are located in Europe. I cannot speak for non-US prices, but here in the US, most demijohn bottles would sell in the $40 to $200 USD range.
Condition is of utmost importance to the collector. Even minor cracks or blemishes hurt the value.
