As a percentage of spot, the "premium" will always be more for copper than it is for silver, simply because silver is currently selling for 6.5 times the price of copper. But that doesn't make the copper any cheaper to process, handle, mint, transport, etc. There are a lot of fixed costs involved in producing bullion regardless of what metal you are working with (and there are some higher variable costs with copper because it melts at a higher temperature and is more reactive to oxygen when molten, requiring more energy to melt and special care when casting). If $0.34 per troy oz over spot is too much, then what would be acceptable?
After reviewing others views on these bars...
viewtopic.php?f=7&t=3504It is the opinion of others on this site that these bars are not seen as investments due to their cost over spot (which this crowd would easily statistically represent the US population that invests in PM's). They are seen more as a novelty (which is fine... if folks are willing to buy them for what others are charging... then who cares why they are buying them right?) .34 over spot is too much over to be seen as an investment. Even the ones that own them admit that. My suspicion is that about 10% to 20% over spot (may be even 50%) would have people look at these as true investments... not 200% over.
