The "S.C.C." chip is probably a country club chip. I bought mine off eBay but the dealer had not info as to source; since he lives in or near Santa Barbara I looked to see what if any city near that town began with an "S" but drew a blank--Salinas, maybe?

Like you, I picked up a number of the chips at the convention so if you get a private identification would appreciate it if you would share it with us.
