While sorting out freshly tumbled LC brass by the year on the head stamps, I found that there are two different head stamps for 14. The "old" looks like the headstamp from 11 and the "new" looks like the headstamp from 15.

Would you worry about separating them as a distinct head stamp for reloading purposes?

The "dots" on the LC 14 cases actually represent something. I don't have the "decoder ring" for 2014, but in past years, the inclusion of dots has meant various things such things as: Brass subcontracted (made at facility other than LCAAP), brass made using different stamping process, brass has extra annealing step, brass made on different production line (i.e., a line typically used for other calibers), etc.

A seriously OCD reloader would sort by headstamp, then sort within headstamps by weight.  I'm a "bit" OCD, but not THAT OCD!  LOL.

Thanks RJ, your post got me digging deeper and I found a post on arfcom by 1Devildog.

"The term is SCAMP. Small Caliber Ammunition Modernization Program. The dots are used to identify the station of the rotary loading machinery that made the case. The system used is based on what is called the "octal numbering system". Each dot has a number value that in various combinations can represent each number up to 24. Various combinations of dots equal various numbers which can be tracked back the the specific station of the rotary press if there were case-related QC issues. You can also see this on some Israeli ammo, either dots or early on, numbers in place of the dots. This machinery was also sold to other countries like Taiwan, Australia, etc... but not all used the numbering element on the headstamps. "

So, my best guess is that some of my brass was made on the SCAMP equipment, and some wasn't.
