Well, I have been perusing eBay fo a while now, and noticed that people are falling for the worst investment types ever. They are buying typically 1oz. Copper Bullion for around $3-$4 depending. Take this for example, a 16oz. Copper Bullion Bar going for $10.00 at the time of posting. That's almost a 250% increase for the seller. http://cgi.ebay.com/2011-BUFFALO-CO...617?pt=LH_DefaultDomain_0&hash=item1e621b2f41 Just my heads up, pay attention to prices, and especially quantity when buying around places like eBay.
The real problem behind that is that the base metals aren't valuable enough to make it economical to make them into nice looking bullion bars like that. The cost of producing the bars is most likely the bulk of the premium price involved in a purchase like that. Of course you should shop around and find the best price, though, you can do better if you look around. With a buy like that, even if the price does go up 250% you still probably won't even break even when you sell.
I do not think I could buy something like this off of ebay. I would be too scared that I would get ripped off.
Sometimes, you also see really good deals, just the shipping charges the seller tacks on are a bit ridiculous. The shipping is what breaks the deal for me in most cases.
It's not exactly a good idea to buy common metals as an investment. I wouldn't buy a bar of iron as an investment, nor copper bars, nor nickel, nor aluminum. Gold, silver, platinum, palladium, and a few others are the ones to look into. Copper is a construction and electronics material, and while it is valuable it's generally only profitable if you're salvaging it.
Well no kidding I would never ever ever pay for something, that is really overpriced. Go down to the scrap yard and you can get 5 times more pounds of copper than you can buy on Ebay plus you have to deal with shipping charges on Ebay.
