Treasure

Treasure is normally seen as a collection of gold and/or silver, or even valuable gem stones hidden somewhere waiting to be discovered. However Treasure can refer to anything valuable from an old vase worth millions to a vow between friends or a memory of an experience. Sometimes what one person may consider to be a treasure, others may not hence the phrase: "One person's trash is another man's treasure". Generally, a treasure is something that a person is not willingly to give up without a fight.

One Piece
In One Piece, the idea of treasure has been raised a number of times. While most like Buggy or Nami value gold, silver and jewels, there are others who hold other treasures dearer to their heart:


 * Luffy considers his Straw Hat his treasure because of his promise to Shanks.
 * Zoro considers his vow with Kuina to become the best Swordsman a treasure and carries her sword with him always.
 * Robin considers history more valuable then gold and to her there is no bigger crime then destroying something from long ago such as a set of ruins.
 * Sanji considers his hands to be his treasure because, as a cook, he would be unable to preapre meals if anything happened to them, hence his kick based fighting style
 * Nami considers money and her tangerines to be treasure.
 * Chopper's hat and flag are his treasures because Dr. Hiluluk gave them to him. He also considers human life and proper treatment to be a teasure of sorts. When Dr. Hogback struck Victoria Cindry, Chopper became angry and attacked, seeing Hogback, who used to be a doctor and was supposed to help people with their problems, disregard his vow for human life.
 * Usopp considered Going Merry to be a treasure, not only to himself, but the entire Straw Hat crew. When he found out it was damaged beyond repair, he became angry and got into a fight with Luffy
 * Brook considers his afro a treasure because it's the only thing Laboon would recognise him by.
 * Gaimon considered the animals on his island a treasure after finding out the treasure he was guarding for 20 years was already gone before he got there.
 * Boodle, the mayor of Orange Town considered his town his treasure and was willing to fight Buggy for it.
 * Crocodile considered Pluton a treasure as it was the key to his dreams of conquering the world.
 * To the Shandians their former home of Shandora was their treasure and they were prepared to die for just one bag of Vearth.
 * Ace, before exhaling his last breath, thanked his brother and his Nakama for loving him despite his blood, suggesting that those relationships were to him more precious then any amount of gold, a trait he had in common with his captain Edward Newgate.
 * Edward Newgate considered his pirate crew and allies as his treasure, so his treasure was family.

One Piece itself is named after the treasure of the late Pirate King Gol D. Roger. The biggest mystery (after its location) is what it is.

Treasure Maps
A map is a diagram or graph designed to show the locations of things as they lay on the landscape, such as where forests or villages are located. They are normally used as a guide to get from one location to another with or without the aid of a compass. In the world of One Piece, they normally take the form of a treasure map or island map.

Trivia

 * Despite their association and love for plunder and treasure, most pirates were broke and had little treasure at all to be found. This was because most of what they stole was usually spent on either drink, prostitutes or gambling.
