Is a Donnay 320/340/380? worth anything?

I can't remember what exactly was the number on the racket. I saw it at the local thrift store. It looked cheaply made... but it was definitely a racket from the late 80s or early 90s. It was about 93-95 sq.in., about 22-23mm thin beam, and it had a cheap-looking (plastic I think) device (black with orange and yellow stripes) on the top of the throat. It had a leather grip too. It came with a pinkish color funny-looking Donnay big tennis bag. Is it worth buying it (to sell it)?

Show me a picture if you can, and I'll be able to identify it.

Here, I found a picture of it in the Post Pictures of your Rackets thread. It's the Donnay on the very left side of the first photo:

It looks like a GT model which were very famous in the early 80's and were midsize not midplus. These rackets you dont buy to sell but to keep...
