Best thing to do: forget about them. If and when the time comes, you'll know what to do. Glance at when they expire, mark it on your calendar, and when you're within a year or so of that date, if you're still in business, consider it. More often than not, they'll be worth little to nothing (especially once you factor in any taxes that come along with them). Don't waste time or energy trying to figure out how much they're worth, because it'll change a thousand times before you actually do anything with them.
