How much is this soda worth?!

I have a bottle of green label art mountain dew. I bought it a few years ago for $1.50. I know it collectable and i tried to find it but i only found a different design. It was orange with claws and somebody was selling it for $30. I even used the amazon app and used the barcode on the bottle. Its black and white, swirly design, with lips, and eyes. How much is it worth?
