Some states have laws providing that points are not assessed for minor speeding. On freeways in the daytime the tolerance is 5 MPH in Colorado, Florida, Michigan, Missouri, Pennsylvania, New Mexico, North Dakota, and Wyoming; 10 MPH in Kansas, Kentucky, Oklahoma, Montana, and West Virginia; and 15 MPH in Georgia.
Since there are 100 cents in a dollar and a nickel is 5 cents, and 20 times 5 is 100, then there are 20. there you go. None. A dollar is an entity by itself. While 20 nickels add up to a dollar, it is not a dollar. Oh, yes it's true that 20 nickels = 1 dollar($).
You are getting a lost of misinformation here. Quarters and dimes were made out of 90% silver and 10% copper in 1964 and earlier. Nickels are normally made from a nickel alloy. During World War II nickel became crucial to the war effort. In substitute of the nickel alloy the coins were made of 56% copper, 9% manganese and 35% silver. The mint mark on these coins was also moved from the obverse to the reverse and can be found located above the Monticello building. Also, the nickel design was the same from 1937 until 2004. You can still find silver nickels in circulation. Good luck!
