Problem: Unlike the Spanish milled dollar the U.S. dollar is based upon a decimal system of values. In addition to the dollar the coinage act officially established monetary units of mill or one-thousandth of a dollar (symbol ), cent or one-hundredth of a dollar (symbol ), dime or one-tenth of a dollar, and eagle or ten dollars, with prescribed weights and composition of gold, silver, or copper for each. It was proposed in the mid-1800s that one hundred dollars be known as a union, but no union coins were ever struck and only patterns for the $50 half union exist. However, only cents are in everyday use as divisions of the dollar; "dime" is used solely as the name of the coin with the value of 10, while "eagle" and "mill" are largely unknown to the general public, though mills are sometimes used in matters of tax levies, and gasoline prices are usually in the form of $X.XX9 per gallon, e.g., $3.599, sometimes written as $3.59910. When currently issued in circulating form, denominations equal to or less than a dollar are emitted as U.S. coins while denominations equal to or greater than a dollar are emitted as Federal Reserve notes (with the exception of gold, silver and platinum coins valued up to $100 as legal tender, but worth far more as bullion). Both one-dollar coins and notes are produced today, although the note form is significantly more common. In the past, "paper money" was occasionally issued in denominations less than a dollar (fractional currency) and gold coins were issued for circulation up to the value of $20 (known as the "double eagle", discontinued in the 1930s). The term eagle was used in the Coinage Act of 1792 for the denomination of ten dollars, and subsequently was used in naming gold coins. Paper currency less than one dollar in denomination, known as "fractional currency", was also sometimes pejoratively referred to as "shinplasters". In 1854, James Guthrie, then Secretary of the Treasury, proposed creating $100, $50 and $25 gold coins, which were referred to as a "Union", "Half Union", and "Quarter Union", thus implying a denomination of 1 Union = $100.

Problem: (CNN) -- Lewis Hamilton endured a nightmare start to testing his new Mercedes after driving straight off the track at Jerez on his first day following a hydraulic problem Wednesday.

The 2008 world champion, who left McLaren at the end of last season, was on his 15th lap of timed testing when his car went off the track and hit a barrier of tires.

Hamilton's accident, which prevented him from returning to action, follows teammate Nico Rosberg's disastrous run which was ended by a minor fire Tuesday.

The German's car was found to have been suffering with electrical problems, while Mercedes took to Twitter to give an update on Hamilton's setback.

"Lewis suffered a loss of rear brake pressure, the front brakes enabled him to slow the car but he couldn't avoid the barrier," said Mercedes on Twitter.

"Obvious damage to the front wing and nose; we're checking the car over now. Lewis himself is fine.

"Update from Jerez, we have traced the problem to the hydraulic brake line connecting to the right-rear caliper."

Hamilton is expected to return to the track on Friday following the collision, which saw the car career on straight for some 70 meters at 280 kilometers per hour.
