You can get any essence, the candycane/christmas items (BoC), polar/reindeer mounts, snowballs, NCP beans, bombs, dynomite, etc.
There's been like 5~ Styg ess found so far and it's only day 3.
I personally have found dae ess, 3 mounts, 18k leaves (lol), and a bunch of the other crap.
Every 2 seconds someone shouts that 'OMG I ONLY GET DYNOMITE'... so it's fairly common to get them apparently. But people who have amassed like 100 presents have found BoC/Styg while others (like me) who have gotten thousands have gotten crap. So it's totally just luck... but why is everyone complaining about free crap?
