Don't polish and don't junk. It's an Aesthetic period piece and if you search for aesthetic silver plate you'll find similar items on ebay. List as such put it up on a high starting bid and you should get it sold when the right buyer does along . Looks like if you wait you could get about 50 - 75 for it, unless it's something special and it could go much higher.
Btw I see nothing ugly about that. It's a very nice, unique looking antique that's well ov er 100 years old and would be at home on any victorian sideboard.
