Is this worth anything

[notoriouslyKEN]

I got this glass fish from my grandmother a while ago and it has been sitting in my house. While it's cool, I don't really want the thing and am contemplating selling it. I have heard that it is worth good money, but have no clue what to offer it for. It is just under 2 feet tall and probably weighs 15-20lbs. The sticker on it says vetri murano and it has a 010 on it (maybe the 10th one made??) Anywho here are the pics:

Hi!
The 10 stands for the manufacturer. I just learned about this and I only know that Vetri Murano 22 is Venini. Good luck!

The label is the seal of the consortium of Murano glass manufacturers, which denotes its authenticity, which is a plus. Labels that verify authenticity have a strong effect on value, believe it or not....Im not certain which mfr #10 represents, at one point I had a photo and list of most of them, but I will try to find it.

I found a signature on the bottom of the base as well. I can't really make out who signed it. It looks like "Jarret, L" or "Zarretti, L" or "Jauctt, L" or some combination of the 3. I couldn't get the signature to come out on the image, but if I can find out what the 010 is, I might be able to decipher it from a list of their artists.

Its probably Zanetti. Which makes sense to me as they do a lot of work with clear glass. I will try to confirm the "10" for you, but im almost positive it Zanetti. Try this site:

I did a little research on zanetti and I think I know who the signature belongs to. I think it is Oscar Zanetti's son Licio. Now that I know the signature, it is much easier to read. Now all I need to determine is the value. I might try to take it an antique shop tomorrow just to see what they say.
