Originally, a metre was defined as 1/10,000,000th of the distance from the Earth's equator to the North pole. Since 1983 it has been defined as:
the length of the path travelled by light in a vacuum during a time interval of 1/299,792,458th of a second.
Since 1983 the meter has been defined as the distance light.
Since 1983, the meter has been defined as "the length of the path traveled by light in a vacuum during a time interval of 1/299,792,458 of a second."

Velocity of light in a vacuum is exactly 299,792,458 meters per second. This in fact arises from the definition of the meter since 1983.
Dimension change due to temperature fluctuation (expansion and contraction) would be one.
Subramanyan Chandrasekhar won The Nobel Prize in Physics in 1983.
My suggestion would be to calibrate your scale against known weights, including other US coins. Standard nickels weigh 5 gm, cents dated 1983 and later are 2.5, dimes are 2.27, quarters 5.67 and dollars 8.1 gm.

From Wikipedia: "Since 1983, [the metre] is defined as the distance travelled by light in vacuum in 1⁄299,792,458 of a second." This is the currently used definition.

There are several standards of measurement: weight, length, time to name a few. The standard for weight is the kilogram. The standard was made in London and has been stored in Paris since 1889. See this NPR article for a recent update (8/20/2009): http://www.npr.org/templates/story/story.php?storyId=112003322 The standard for length is the meter, or metre. Until 1983, this standard was a platinum-iridium bar that rested next to the kilogram standard at the French Academy of Sciences. In 1983, the metre was redefined as the distance travelled by light in free space in 1⁄299,792,458 of a second. http://en.wikipedia.org/wiki/Meter The standard for time is the second. "Currently, the international unit of time, the second, is defined in terms of radiation emitted by caesium atoms." http://en.wikipedia.org/wiki/Time Most standards are abstracts, with qualities or characteristics not affixed to a particular object or instance, such as a number. These standards have no place to be kept, except in the imagination of those who conceive of them.
The metre was originally defined as one ten-millionth of the distance from the North Pole to the equator, at sea level along the meridian that passed through Paris. Unfortunately, improvements in metrology meant that a measure that was meant to be a standard was not constant! So, in 1983 it was re-defined as the distance travelled by light in vacuum in 1/299,792,458 of a second
