Collision protects you and your car if you are in an accident, liability protects whomever you may hit.
The personal liability portion of your car insurance is for damage you may cause to others. The collision portion of your car insurance is for your vehicle. If your vehicle is very old, with lots of miles and is not worth much, you may consider not getting it.
How much will it COST? If you have a good record of several years without claims, your premiums may not increase, but if you are a new driver or have had prior claims the increase will be determined by your insurer and no one else can give you a definite answer.
