you're confusing 2 things. before passover, Jews make a declaration claiming that all crumbs and other hametz not found should be like dust.

if however someone had something valuable, like a bottle of whiskey, then they sell it.

Looked it up. You are right..."sell" it, as in the temporary sale I mentioned above. Reference:

And of course, selling the White House chametz:
