I check the TP on every green I pick up, because some of them sell for 2-4 silver a pop. The rest of them goes to the vendor. All light armor gets salvaged into cloth scraps, which gets sold on the TP. Since my material slot for copper/iron/silver ore and the first two tiers of lumber, I sell all of that. I also sell all unidentified dyes, although they've dropped by about 2 silver over the last week and a half.
I hear that people can make something like 1.5g an hour by doing events in Orr, but I wouldn't know from personal experience.
