Currently printed denominations are $1, $2, $5, $10, $20, $50, and $100. Notes above the $100 denomination stopped being printed in 1946 and were officially withdrawn from circulation in 1969. These notes were used primarily in inter-bank transactions or by organized crime; it was the latter usage that prompted President Richard Nixon to issue an executive order in 1969 halting their use. With the advent of electronic banking, they became less necessary. Notes in denominations of $500, $1,000, $5,000, $10,000 and $100,000 were all produced at one time; see large denomination bills in U.S. currency for details. These notes are now collectors' items and are worth more than their face value to collectors.
What was issued to halt the use of higher currency denomations?
an executive order

Although Whig grandees such as Portland and Fitzwilliam privately agreed with Burke's Appeal, they wished he had used more moderate language. Fitzwilliam saw the Appeal as containing "the doctrines I have sworn by, long and long since". Francis Basset, a backbench Whig MP, wrote to Burke: "...though for reasons which I will not now detail I did not then deliver my sentiments, I most perfectly differ from Mr. Fox & from the great Body of opposition on the French Revolution". Burke sent a copy of the Appeal to the king and the king requested a friend to communicate to Burke that he had read it "with great Satisfaction". Burke wrote of its reception: "Not one word from one of our party. They are secretly galled. They agree with me to a title; but they dare not speak out for fear of hurting Fox. ... They leave me to myself; they see that I can do myself justice". Charles Burney viewed it as "a most admirable bookthe best & most useful on political subjects that I have ever seen" but believed the differences in the Whig Party between Burke and Fox should not be aired publicly.

Gaddafi financially supported other militant groups across the world, including the Black Panther Party, Nation of Islam, Tupamaros, 19th of April Movement and Sandinista National Liberation Front in the Americas, the ANC among other liberation movements in the fight against Apartheid in South Africa, the Provisional Irish Republican Army, ETA, Sardinian nationalists, Action directe, the Red Brigades, and the Red Army Faction in Europe, and the Armenian Secret Army, Japanese Red Army, Free Aceh Movement, and Moro National Liberation Front in Asia. Gaddafi was indiscriminate in the causes he funded, sometimes switching from supporting one side in a conflict to the other, as in the Eritrean War of Independence. Throughout the 1970s these groups received financial support from Libya, which came to be seen as a leader in the Third World's struggle against colonialism and neocolonialism. Though many of these groups were labelled "terrorists" by critics of their activities, Gaddafi rejected such a characterisation, instead considering them revolutionaries engaged in liberation struggles.
During what conflict did Gaddafi notably switch sides?
Eritrean War of Independence
