My uninsured vehicle was hit by a insured vehicle

Although you're required to carry at least liability insurance in California, your uninsured status shouldn't affect your ability to have a claim paid out. In terms of what you will receive for your vehicle, you will most likely be cut a check for the actual cash value of the vehicle. Meaning, you will be paid what your vehicle was worth before the accident - not what it will take to get a new vehicle. This is pretty standard for most car insurance policies.
