Once you have a cracked tank, it's got to be repaired before it can be used. The cost of the piece of glass is often more than the original price of the tank. It's also a massive amount of work to remove the bad piece of glass and install a new one.
You might give it away if someone wanted it for a planter or willing to invest the time and effort to repair it. However, I think your better off just getting rid of it.
Or a reptile tank!
