In India, rupees are mainly used for currency. 49 62 rupees is approximately equal to $1 USD. The extremely high prices of tradable goods in Hyrule are explained by the fact that someone can find a rupee under a rock, in a bush, in the corpse of a dead cucco, almost anywhere. Since the overabundance of rupees has caused terrible inflation in Hyrule, Hyrule simply trades with itself.
