I'm actually a big fan of coins having weight, mostly because it makes sense but also because it makes sentences like, "Adventurers love gems because they're small, light weight, and easily concealed compared with the same value in coins," mean something. And if coins don't have weight, then items made of similar materials shouldn't, either, so walking out of lost dungeons and forgotten temples with huge solid gold statues shouldn't be any effort, even for crippled Brownies. Treasure is treasure and gold is gold, right?
