Rupee

Rupees are the unit of currency within most of the Zelda universe, within circulation in the lands of Hyrule, Koholint Island, Termina, Labrynna, Holodrum and The Great Sea. Rupees are acquired primarily by defeating enemies, by cutting tall grasses or bushes, or by opening treasure chests, and used primarily to purchase items in shops.

Values
With the exception of The Adventure of Link and Four Swords Adventures, Rupees are included in all The Legend of Zelda titles. The value of a Rupee is denoted by its color, but the value of each color is inconsistent throughout the games. In Four Swords and The Minish Cap, both size and color denote value. Link's Awakening, Oracle of Ages, and Oracle of Seasons specify the Rupee value through text rather than color, because the Game Boy palette was limited; however, in the Oracle games, Link could find a larger rupee by digging with his shovel. The Wallet’s capacity ultimately determines how many rupees one may receive even when finding Huge Rupees. The following lists Rupees by their values by the games they appear in.

Link’s Crossbow Training
By breaking certain pots in Link’s Crossbow Training an Orange Rupee will be released. These Rupees are initially worth 1000 points but their point value will decrease the longer it stays on-screen.

Freshly-Picked Tingle's Rosy Rupeeland
In Freshly-Picked Tingle's Rosy Rupeeland, Tingle uses Rupees as health. They come in similar values as in normal Zelda games. However the colors don’t necessarily have specific values. When Tingle picks up a red, purple, or orange Rupee, he will usually get 20, 50, or 100 Rupees, respectfully. However, it is possible to get a red, purple, or orange Rupee in other values, such as 21, 57, or 109.

A main part of Freshly-Picked Tingle’s Rosy Rupeeland is negotiating. When Tingle is either paying for information or items, or receiving a reward or selling certain items, he is asked to negotiate a price. Negotiations are done-using a calculator on the touch screen. The amount of Rupees Tingle can receive can vary depending on his progress in the game.

Super Rupees and Master Rupee
During Tingle’s quest to reach Rupeeland, Tingle obtained the five Super Rupees and eventually the Master Rupee in the Auros Ruins. The Super Rupees have no value, but are said to contain mystical powers. The five Super Rupees are the Metal Rupee, the Aqua Rupee, the Leaf Rupee, the Earth Rupee, and the Magma Rupee.

Rupee Thieves
Rupee thieves appear in several games. When they come in contact with Link the will either cause his Rupees to fly out of his wallet onto the ground (like Thieves and Keatons,) or will drain or steal the Rupees straight from his wallet (like Rupee Likes and Takkuri.)
 * Known Rupee thieves:
 * Rupee Like
 * Thieves/foxes
 * Takkuri
 * Rupee Wraith
 * Keaton
 * Rats

Trivia

 * In The Legend of Zelda, Rupee was spelt "Rupy". In the manual, it was "Ruby".
 * The Rupee is the real-world currency of India, Sri Lanka, Nepal, Pakistan, Mauritius, the Seychelles, and Maldives. It used to be currency in Bhutan as well.
 * The Silver Rupee’s low value in Ocarina of Time is due to the fact that the Silver Rupee's only purpose in the game was as a puzzle element, and not an actual spending Rupee. These Rupee puzzles can be found in Ice Cavern, the Shadow Temple, the Spirit Temple, and inside Ganon’s Castle.’’)
 * In Majora's Mask, there appear to be two differently-colored Huge Rupees: one given to Link by a Deku Scrub, and one earned by killing the Takkuri, although this one is not accompanied by text, so its title as a "Huge Rupee" could be debated.
 * In Majora's Mask, the probability of finding a Red Rupee in grass is high if Link has less than twenty rupees in his wallet.
 * When using the Salvage Arm in Phantom Hourglass, there may be a few valuable rupees in bubbles. If the back arrow is pressed before reaching the treasure chest and you choose to salvage again, all the rupee bubbles will be back. This is an effective way to get infinite rupees.
