费城 - 2010年的客场之旅的最佳地区之一,越来越去了不起的地方在后面的情景,常常得到更密切的行动比通常是可能的。 



PHILADELPHIA--One of the best parts of Road Trip 2010 is getting to go behind the scenes at terrific places, and often getting much closer to the action than is usually possible.

On Wednesday, CNET reporter Daniel Terdiman completed a two-part set of visits to the production facilities for America's money. First it was the U.S. Bureau of Engraving and Printing's next-generation $100 bill production process, in Washington, D.C. On Wednesday, it was the U.S. Mint here, to see how coins are made.

Pictured is a bin full of thousands of blank dollar coins. These blanks will go through several steps before being fed into a press and emerging as dollar coins.

The Mint presses 750 coins a minute, and these days is producing 20 million coins a day, though its full capacity is higher, as much as 50 million coins daily. That number is lower today, because of the state of the economy, and lower demand for new coins.

生产过程是大致相同的所有美国硬币这些天来,尽管一些设计师仍然工作在粘土为主,而其他人使用如Adobe Illustrator或Photoshop软件工具。 

对于第一个步骤,一个设计师,在这种情况下,艺术家菲贝亨普希尔证章,工程对新硬币的设计在Photoshop。在这里,她显示了一个特殊的纪念奖章 - 这也使得美国造币厂设计,除了那些在流通硬币投入 - 歌颂旅。
The production process is pretty much the same these days for all U.S. coins, although some designers still work mainly in clay, while others use software tools like Adobe Illustrator or Photoshop.

For the first step, a designer, in this case medallic artist Phebe Hemphill, works on the new coin's design in Photoshop. Here, she shows the design for a special commemorative medal--which the U.S. Mint also makes, in addition to coins that are put in circulation--honoring the Tuskegee Airmen.

Next, the artist uses the design from Photoshop and produces a clay cast of the future coin, as seen here.

The next step is to take the clay cast and use it to produce a negative cast in plaster.

The next step after the negative plaster casting is to produce a final positive plaster casting. This will be used as the basis for the coin, or, in this case, medal.
