I also got into the game at the beginning of this year. I have the core set, Mirkwood cycle, Khazad-dum and Dwarrowdelf, Heirs of Numenor and Against the Shadow, and both Hobbit expansions. Everything had the gold rings except HoN and the AtS APs, which I bought from CSI. They all had a Jan 13 date. They did not have the gold rings but did have the errata text.
The errata text is the only thing I really care about as I can use the Easy Mode pdf on FFGs website and remove the extra cards.
Could you check and share what the dates are on both of your "Hobbit" expansions/boxes ?
