I'm mostly a fan of simpler metals, like aluminum, steel and titanium. I need to see it formed into something, this calms my mind

It's a pleasure to talk to you, because you seem to understand the game. Even if our views on some things are different, it doesn't matter, because we are able to express ourselves in a respectful and constructive form.
I'm not proud of it, but I mostly come here to troll. Religious people have always brought out the troll in me, and I haven't found a better way to converse with them yet. From time to time, it's a pleasant surprise to see that you can actually express yourself as an human being and it will be understood.
Those metals are not great for stacking though as they are not value dense if you hold the physical metal.
Silver is bad enough but you can cram a lot of money in gold form into peli case
