   It is on that page - you have 1958 KN
For coins with H it is after only S of CENTS
For coins with KN after N of TEN is letter K and after S of CENTS is letter N
So a coin with H only has the letter appearing once - it is not on there twice.
 Otherwise it would be called HH mintmark.  

P.S. They are both Birmingham, UK mints as in H = Heaton, KN = Kings Norton.

OK
 Forgive my ignorance
