Hey, I have this 1963 error coin book by Michael Kolman, Jr. called "The numismatic Flying Eagle, Indian and Lincoln Cent Errors " !.
Do they measure Off Center errors like this ? Or just Percentages ?

Hmm this is the first time that the word "kolit" has ever been used on CCF. So that I can learn, can you please describe this device in more detail? Personally, I've only even seen percentages used.

I made a GIF image last year to help identify the percentage off center on coins. It's in 1­­% graduations and gives a rough idea of the offset.

I had to reduce the size and desaturate the color so I could post it here, but I have a full size version that's 6.4 mb if anyone want's a copy.

It's a Kolit Gauge that measures as a fraction . Example 1/4 O.C , 1/8 O.C
I wish I could take a photo but gauge is too big . It's like what you showed but in terms of fractions like I showed examples of . I guess after awhile you can eyeball it, nThere was something called a Kolit gauge which was used to both specify the direction in which a coin was off center and to determine the percentage. The directional gauge was like a clock, it is why many old time collectors will refer to positions on a coin as "K-8" or "K-10". The off center gauge was a series of arcs showing the area of a struck coin in 10% increments. The same gauge could be used to determine the amount of material missing in a large clipped planchet.o ?

Very nice Yoko. Subtract from 100 and can determine the amount of clipping too.
