The use of K:# started in the 60s when a pair of professional numismatist came up with a reference tool that came to be called the Kolit Position. It's the combination of their last names Kolman and Litman shortened to "Kolit" and then followed by a number from a clock face.
It's common for collectors to use the K: to represent the Kolit position with a clock face numeral.
I see by the clock now that it's after K:12, so I'm off to bed.
