For fun, but I see nothing wrong with making gold as well.
By the time the most recent Halloween event had rolled around I'd saved up in excess of 100 decayed orr emblems, which earned me a bit when I stood around in LA offering to sell 5 each for 300g or something.
Similarly the lack of dust in this Canthan event. Materials was buying for 150, selling (when it was in stock) for 250. So I stood around offering to sell 10 per 200g.
Also sold my first pig for 10k, since I was fairly sure I'd be getting at least one more before the night was over...
