After about 10 hours of afk whacking the tree of fortune these are the results. On top of that I got about 7k of raw gold from opening the packets.

Big hits were the letter cards that sell for 10k each. Aside from that the travel tickets at the top sell for 250 and the various food has values around 20-250.

I don't know if any of this has ingame use beyond vendoring but if you can leave your client open when you're not playing then might as well do this I guess.. Maybe there are better ways of making money that make this irrelevant.
