The Orange Rupee, a rupee saved is a rupee earned.
Rupee’s are always changing in the Zelda Timeline from age to age. By the time of The Original Legend of Zelda all but two types of rupees remain. The orange rupee in other timelines is worth 100, but at this time it’s worth a buck. Which begs me to ask the question who cuts the rupees and determines their value? Sounds like that would be a great side plot to explore for future games. The proportions from the 8 bit and game manual image was use to design the orange rupee. Don’t spend it all in one place.
