Hello. I did some research on your painting inquiry.
I found 2 appraisers in Californina. The first of which is:
CATHERINE LEONHARD
American and California Paintings Specialist
Christie's
360 North Camden Drive
Beverly Hills, CA 90210
(310) 385-2600
cleonhard@christies.com
Of the two she is the shortest distance. Her wesite
http://www.christies.com/home_page/home_page.asp, gives further details. Her focus is primarily on American and Califorian paintings. She also auctions painting on a comission basis.
Second, we have:
PETER M. FAIRBANKS
President
Montgomery Gallery
406 Jackson Street
San Francisco, CA 94111
(415) 788-8300 (phone)
(415) 788-5469 (fax)
paintings@montgomerygallery.com
Granted you would have a 5 1/2 hour drive on your hands, but the 2nd opinion would be beneficial. His business places focus on California artists as well. In addition, he does offer conservation/resoration services. His wesite,
http://www.montgomerygallery.com/, can provide further deetails.
Both of the aforementioned experts offer the appraisal service you seek.
Whether or not you should auction, sell outright, or through a gallery show really depends on the particular artist and condition or the painting. I don't mean to be so general, but for the answer you seek a paint expert such as Ms. Leonhard or Mr. Fairbanks should first be consulted.
Tears can be restored. Following is a link to some examples which are representative of another conservators work:

Keep in mind that Mr. Fairbanks does offer resoration services. Hence, he would be better to assist you in a situation such as this.
If you have any further questions, please let me know
Good luck,
