I believe the total is 270 total chips + 2 plaques. I rounded down to 260.

CHIPCO samples. Vast majority are $5 chips, notched with a CHIPCO ad on the reverse.

I have broken them down as follows:

FOREIGN CHIPS = 110
CHIPS I CAN’T FIGURE OUT = 36
NEVADA (NON-VEGAS) = 29
U.S.A. (MISCELLANEOUS) = 23
WASHINGTON STATE (USA) = 17
WET CHIPS (CRUISE & RIVERBOAT) = 16
NEVADA (LAS VEGAS) = 16
PROMO/AD CHIPS = 15
CHIPCO ADVERTISING CHIPS = 8 + 2 plaques

$270 shipped USPS Priority Mail within the USA.
