Gold Silver Cross

What does 14KN mean on a gold cross?

I have a gold cross with a silver Jesus that is marked 14kn. Is this filled or something?

14K means there are 14/24ths gold in it and 10/24ths other metal. The N is a alloy desigator, so a jeweler who needs to make it bigger can match the alloy. It's like a dye lot code for gold. Different alloy mixes have slightly different colors.
