Been collecting for awhile but I continue to see this phrase (from K-7)  pop-up occasionally on other sites when comparing my finds to online databases. I'm not completely sure what it is referring to.  Tried to google it but haven't found a definition or description as to exactly what this means.  Here's a copy and pasted example from coppercoins.com

Strong doubling from K-7 shows on all upper reverse details

Thanks for your comments!

I believe it refers to a clock position; 7 o'clock would thus be at the lower left on a coin or medal. In the instance cited by the poster, K-7 refers to the pivot point from which the doubled image emanates, so this doubling would become more pronounced the further it is from that position.

Years ago there was a device for measuring degrees of rotation between dies, or the Kolit Scale. Evidently, Kolit was the fellow who created this tool, and the K positions are still used by some. I'm not certain whether this use of "K" applies to the example cited.

One of the best answers EVER.

Kolit's device was also Kosher ('K') for those who served it as an entree.

Thank you very much DWLange.  That is some good information.  I assumed it was referring to some type of an orientation on the coin but I was just not sure of the exact meaning.  Here is the link from copper coins which I was referring to regarding the K-7.
