Silver

According to something I read, the demand for silver has exceeded supply every year since 1990. I never thought about this before. I think of silver in terms of jewelery, but apparently some people buy it as coins or ingots for trading purposes. I just can't wrap my head around why this is important to anyone. Precious metals are harder to find than rocks, therefore they have much more value. But what good are they... they just symbolize some kind of value like paper money. I guess I'll just never understand. But it doesn't matter, because the trade of silver and other precious metals will go on.
