The Nobel Prize in Physics is an annual award given by the Royal Swedish Academy of Sciences for those who have made the most outstanding contributions to mankind in the field of physics. It is one of the five Nobel Prizes established by the will of Alfred Nobel in 1895 and awarded since 1901, the others being the Nobel Prize in Chemistry, Nobel Prize in Literature, Nobel Peace Prize, and Nobel Prize in Physiology or Medicine.

The prize consists of a medal along with a diploma and a certificate for the monetary award. The front side of the medal displays the same profile of Alfred Nobel depicted on the medals for Physics, Chemistry, and Literature.

A medal or medallion is a small portable artistic object, a thin disc, normally of metal, carrying a design, usually on both sides. They typically have a commemorative purpose of some kind, and many are presented as awards. They may be intended to be worn, suspended from clothing or jewellery in some way, although this has not always been the case. They may be struck like a coin by dies or die-cast in a mould.

A medal may be awarded to a person or organisation as a form of recognition for sporting, military, scientific, cultural, academic, or various other achievements. Military awards and decorations are more precise terms for certain types of state decoration. Medals may also be created for sale to commemorate particular individuals or events, or as works of artistic expression in their own right. In the past, medals commissioned for an individual, typically with their portrait, were often used as a form of diplomatic or personal gift, with no sense of being an award for the conduct of the recipient.

The United States ten-dollar bill (US$10) is a denomination of U.S. currency. The obverse of the bill features the portrait of Alexander Hamilton, who served as the first U.S. secretary of the treasury, two renditions of the torch of the Statue of Liberty (Liberty Enlightening the World), and the words "We the People" from the original engrossed preamble of the United States Constitution. The reverse features the U.S. Treasury Building. All $10 bills issued today are Federal Reserve Notes.

As of December 2018, the average life of a $10 bill in circulation is 5.3 years before it is replaced due to wear. Ten-dollar bills are delivered by Federal Reserve Banks bound with yellow straps.

The United States one-dollar bill (US$1), sometimes referred to as a single, has been the lowest value denomination of United States paper currency since the discontinuation of U.S. fractional currency notes in 1876. An image of the first U.S. president (1789–1797), George Washington, based on the Athenaeum Portrait, a 1796 painting by Gilbert Stuart, is currently featured on the obverse, and the Great Seal of the United States is featured on the reverse. The one-dollar bill has the oldest overall design of all U.S. currency currently in use. The reverse design of the present dollar debuted in 1935, and the obverse in 1963 when it was first issued as a Federal Reserve Note (previously, one-dollar bills were Silver Certificates). The current US two-dollar bill has the oldest obverse design, dating from 1928.

A dollar bill is composed of 25% linen and 75% cotton. That blend makes the notes more difficult to counterfeit compared to paper (as well as increasing its durability). As of December 31, 2018, the average life of a dollar bill in circulation is 6.6 years before it is replaced due to wear. Approximately 42% of all U.S. currency produced in 2009 were one-dollar bills. As of December 31, 2019, there were 12.7 billion one-dollar bills in circulation worldwide. An engraver at the US Bureau of Engraving and Printing, George Frederick Cumming Smillie, made an etching of a painting of George Washington by Gilbert Stuart which was used on multiple banknotes. A vignette of the portrait appears on the one dollar bill of 1899, and on notes since 1918.

The Krugerrand (/ˈkruːɡərænd/; Afrikaans: [ˈkry.ərˌrant]) is a South African coin, first minted on 3 July 1967 to help market South African gold and produced by Rand Refinery and the South African Mint. The name is a compound of Paul Kruger, the former President of the South African Republic (depicted on the obverse), and rand, the South African unit of currency. On the reverse side of the Krugerrand is a pronking springbok, South Africa's national animal.

By 1980, the Krugerrand accounted for more than 90% of the global gold coin market and was the number one choice for investors buying gold. However, during the 1980s and 1990s, Krugerrands fell out of favor as some Western countries forbade import of the Krugerrand because of its association with the apartheid government of South Africa.
