I'm not there yet, (79.2) but you can actually turn a profit with Panacaea
and platnium nuggets. Especially if you have your goldsmithing to 60 and can synth the nuggets into ingots to sell in stacks. Panacaea sell out on the AH pretty fast, if you don't wanna use them for the nuggets, the only problem is coming up with the philosophers stones for them.
