Crane Potato Chips Pins
 

O.K. Crane Potato Chips guys...the pins from 1961-1965 have the year stamped on the back of the pin. Then there are 3 pins with a blue crane, red crane and orange crane. What years are the pins with the colored cranes stamped on the back? This leaves one year unaccounted for. Did Crane not put a pin out one year? If not, what year am I missing and what color is the pin I'm missing? If anyone can help me out I'd appreciate it. I know there are two pins in the 80's but I'm just looking for the pin I'm missing from the 60's.

No pin in 1966
Blue 1967
Red 1968
Orange 1969

Ted Hakes book, I believe, has 1968 and 1969 reversed.

I have almost 2 complete sets for each year of Crane pins from 1965-69 and looking to complete 1963. Any help? I have dozens and dozens of extras for trade or sale.
