Learned this lesson the hard way, but really have to ask yourself if there is economic value to the name, eg: Will someone need the name to sale, promote, or otherwise have information on the term?
You obviously cannot always predict this with certain accuracy, but it's a good place to start.
With it being a .com, I'd be more inclined to take a chance. If it's another gTLD or ccTLD, it would depend and chances would likely quickly decrease.
