I don't see how that makes the argument of the grandgrandparent post. If some thought had been put into the denominations then what you'd assume to be normalized is purchasing power (since the smallest denominations should correspond to "a fraction of the cheapest thing I could buy" [if we include change] and the biggest should correspond to "more money than is reasonable to carry around for buying stuff"). Following that logic and combining it with yours the conclusion is "100$ in the US has similar purchase power to 15$ in India" or "things are cheaper in India", which really doesn't say much to me.
