I've hunted there It's pretty built up though, with modern amenities, buildings, etc... that no doubt cover the old board-&-batton structures of yesteryear. I just got common silver (& wheaties, etc...) The beach right by there "Asilomar Beach" has been known to spit out old coins after storms/erosion from the right direction. But not that frequently (like, it just erodes down to those "just right" conditions only every 3 or 4 yrs. or so).
