What does the 10KF stamp mean?

[kmoro]

Hi all!

The internet is unclear about the hallmark 10KF … does it mean that it is filled or fine?

Thanks in advance!

If it was filled, it would normally say GF, for gold filled. Are there any other marks or symbols? can we get a picture of it?

Could it say KP?
