I know that copper coins are probably never going to drop below their face value on the secondary market. If copper were to drop down to much, much lower levels however, what would be a good way to stock up on copper in non-coin form?
Standardized bars are sold, I know, but anywhere I've looked, they carry a huge premium above spot price. Is there a particular form of new industrial or scrap copper that can be easily found and sells for close to spot price? I have the same question concerning nickel.
Thanks!
