I have a coin that I purchased years ago that I retained in my collection.  It was labeled KM 619 B from a Mexican Revolutionary coin variety from the State of Chihuahua.  All the research seems to indicate it is a uniface coin variety, but the coin in the holder with the KM 619 B designation is not uniface.  I have not been able to find a picture of the KM 619 B variety.  It is very scarce to rare.  Do you know where I can find out if this was mislabel or find a picture of the coin type?  The NGC registration with pictures is 3481327-069.  Thank you, Art R.

If his coin is just silver it should be KM-619.

We don't use the KM-619 reference anymore for the silver coin - we just use "1915CH FM Mexico Peso Chihuahua Silver" on the tag. 

KM-619B refers to a Brass Uniface coin which is rare.
