One Good Delivery gold bar weighing 12.4キログラム (400 ozt)

金の延べ棒は 金塊(gold ingot)とも呼ばれる金の延べ棒は、製造、ラベル表示、記録保管に関する標準条件を満たす延べ棒製造業者によって製造された、あらゆる形状の精製金属金の量である。溶融金属を鋳型に流し込んで製造される大型の金塊はインゴットと呼ばれる。小型の金塊は、適切に圧延された金シートを鋳造またはプレス加工して製造されることもある。中央銀行が金準備として保有し、地金ディーラーの間で取引される標準的な金塊は、400トロイオンス(12.4キログラム、438.9オンス)のグッド・デリバリー・バーである。キロボルトは1,000グラム(32.15トロイオンス)の質量であり、100トロイオンスの金塊は、より扱いやすい金塊であり、取引や投資に広く使用されている。[1] これらの金塊の取引におけるプレミアムは、金のスポット価格に対して非常に低く、銀行やトレーダー間の少額の送金に最適である。ほとんどのキロボルトは平らだが、特にヨーロッパではレンガ型の形状を好む投資家もいる。[2]

金の延べ棒は A gold bar, also called gold bullion or 金塊（gold ingot）は, is a quantity of refined metallic gold of any shape that is made by a bar producer meeting standard conditions of manufacture, labeling, and record keeping. Larger gold bars that are produced by pouring the molten metal into molds are called ingots. Smaller bars may be manufactured by minting or stamping from appropriately rolled gold sheets. The standard gold bar held as gold reserves by central banks and traded among bullion dealers is the 400トロイオンス (12.4キログラム; 438.9オンス) Good Delivery gold bar. The kilobar, which is 1,000グラム (32.15トロイオンス) in mass, and a 100 troy ounce gold bar are the bars that are more manageable and are used extensively for trading and investment.[1] The premium on these bars when traded is very low over the spot value of the gold, making it ideal for small transfers between banks and traders. Most kilobars are flat, although some investors, particularly in Europe, prefer the brick shape.[2]

製造方法により、金塊は鋳造または鋳造のどちらかに分類され、両者は外観と価格が異なる。鋳造金塊は、インゴットとほぼ同様の方法で製造され、溶かした金を棒状の鋳型に流し込み、固める。この工程では、表面が不均一な形の歪んだ金塊になることが多いが、不完全ではあるものの、それぞれの金塊が唯一無二のものとなり、識別しやすくなる。鋳造金塊は、製造に時間がかからず、取り扱いも少ないため、鋳造金塊よりも安価である。

Based upon how they are manufactured, gold bars are categorized as having been cast or minted, with both differing in their appearance and price. Cast bars are created in a similar method to that of ingots, whereby molten gold is poured into a bar-shaped mold and left to solidify. This process often leads to malformed bars with uneven surfaces which, although imperfect, make each bar unique and easier to identify. Cast bars are also cheaper than minted bars, because they are quicker to produce and require less handling.

鋳造された金塊は、平らな金塊から必要な寸法にカットされた金片から作られる。これらは表面が滑らかで均一であることで識別できる。

Minted bars are made from gold blanks that have been cut to a required dimension from a flat piece of gold. These are identified by having smooth and even surfaces.

Security features

[編集]

To prevent bars from being counterfeited or stolen, manufacturers have developed ways to verify genuine bars, with the most common way being to brand bars with registered serial numbers or providing a certificate of authenticity. In a recent trend, many refineries would stamp serial numbers even on the smallest bars, and the number on the bar should match the number on its accompanying certificate.[3]

In contrast to cast bars (which are often handled directly), minted bars are generally sealed in protective packaging or Tamper Evident Packaging (TEP) to prevent tampering and keep them from becoming damaged. A hologram security feature known as a Kinegram can also be embossed directly on a gold bar. Bars that contain these are called Kinebars.[4]

Standard bar weight units

[編集]
Gold prices (US$ per troy ounce), in nominal US$ and inflation adjusted US$ from 1914 onward

Gold is measured in troy ounces, often simply referred to as ounces when the reference to gold is evident. 1トロイオンス (31.1034768グラム)*. The troy ounce is heavier than the avoirdupois ounce, a commonly used unit for measuring weight in the United States customary system. 1オンス (28.349523125グラム)*.[5]

The standard gold bar held and traded internationally by central banks and bullion dealers is the Good Delivery bar with a 400 ozt (12.4 kg; 438.9 oz) nominal weight. However, its precise gold content is permitted to vary between 350 ozt (10.9 kg; 384.0 oz) and 430 ozt (13.4 kg; 471.8 oz). The minimum purity required is 99.5% gold. These bars must be stored in recognized and secure gold bullion vaults to maintain their quality status of Good Delivery. The recorded provenance of this bar assures integrity and maximum resale value.[6]

  • One tonne = 1,000 kilograms = 32,150.746 troy ounces.
  • One kilogram = 1,000 grams = 32.15074656 troy ounces.
  • One tola = 11.6638038 grams = 0.375 troy ounces.
  • One tael = 50 grams.

It was manufactured by the Mitsubishi Materials Corporation, a subsidiary of Mitsubishi. It went on display at the Toi Gold Museum on 11 July 2005. Its gold content was valued in 2005 at 400 million yen (approximately US$3,684,000 at the time).[21][22][23] 2023年 (2023-Jan)現在, it is worth approximately US$15.1M.[24]
