Tin

This silvery, malleable post-transition metal is not easily oxidized in air and is used to coat other metals to prevent corrosion. The first alloy, used in large scale since 3000 BC, was bronze, an alloy of tin and copper.

The chart below shows prices in "tonnes", which are 1000 kg, or 2204 lbs.  Tin prices were hit heavily along with other commodities.  Compared to other base metals it has a relatively high price (about $9.00/lb vs. $6.30 for nickel) and it has much lower stocks (14000 tonnes vs 186000 for nickel).
