</div>Why does inflation of the US dollar relate to the bet? Was the bet<br>
about how these metals would perform in dollars?<br>

</div>Good data is hard to come by. However, I think you might be able to<br>
normalize it all to gold. Get the spot price for gold and copper on a<br>
given day, and you should have a "value" that is real in some sense.<br>
<br>
The problem is what is the best measure of value, the US dollar? Gold?<br>
The Euro? What question is it that you're actually trying to answer?<br>
<br>
I'm sure you have looked at the chart here:<br>
