There is no such thing as a "correct coin" for 1960 Kodiak, Kodiak Deluxe, or Kodiak Special Deluxe. Some got copper coins, some got aluminum. Mostly likely they were using up the copper coins and installing the aluminum at the same time. There is no rhyme or reason to the coins as they overlap. I have over 20 versions of these 1960 Kodiaks, the serial numbers don't jive like the 1959 Kodiaks and the coins are intermixed.
