Gold,

I guess we would all like some more, 

gold - visualized in Bullion Bars, there's surprisingly little gold in the world if you calculat with gold price at $2000/oz. when gold reaches $3110/oz, 1 oz of gold & one ounce of $100 bills will have equal value in weight and it won't matter if you have 1oz of $100 bills or 1oz of gold, gold is usually measured in Troy Ounces, a Troy Ounce is about 1.09 regular ounces,

1 ton of Gold is worth $64.3 Million dollars at $2000/oz. and above this is what it would look like,  

world banks gold reserves, this gold values shown are official numbers from Wikipedia but there is a strong chance the numbers are inaccurate since western world's Central Banks have purportedly leased out the gold reserves while using accounting tricks to hide the facts, in order to push the gold price down, gold price is an indirect indicator of economic stability, the lower the price, the more stable the global economy appears, also notice the UK is not here, a guy named Gordon Brown sold most of ours at rock bottom prices a number of years ago, but that is another story!

if all the gold ever mined was melted into a solid cube, the cube with sides of 20.5m would fit in an Olympic Swimming Pool, the small gold sphere, in front of the cash couch, weighs 1 metric ton exactly, with a value of over $50 Million dollars, for more great examples of what gold looks compared to everyday objects like this is the place to go, Demonocracy, give it a look it is quiet surprising looking at gold visualized as bullion bars.
