Should I Keep These?

Man I miss Disneyland. Can't wait to go back. I was going through a box in the garage and found these. I had saved them from the first time we ever went to Galaxy's Edge. They are specialty Coke and Sprite bottles. They look like thermal detonators. So cool. But are they collectors items? I guess they are but I am starting to run out of space with all my stuff. Not sure if I should hang on to them or not.
