1 US dollar ≈ 63.7201 Russian rubles.
The main image on the front of the U.S. dollar banknotes is a portrait, and the main color is black. The main scene pattern on the back is a building, and the main color is green, but there are few differences in the colors of different versions. For example, the back of the 1934 version is dark green, the back of the 1950 version is grass green, and the back of the 1963 version is all dark green. Since Dollar Green is an ink made from tree sap, the quality of the sap varies each time so the color is slightly different.
The signature on the U.S. dollar is the signature of the Minister of Finance, and different Ministers of Finance represent different issuance years. Prior to the 20th century, 1, 5, 10, 25, and 50-cent notes were issued. The large-front dollar is one-half the size of the small-front dollar compared to the small-front dollar. Interestingly, all denominations of the U.S. dollar are the same size. The $20 dollar bill is the most widely used high-denomination banknote in the United States.
