not all coins just the penny
Simple answer: All coins are graded by the same scale. Circulated coins by how much wear the coin has. Uncirculated coins by how well the coins are struck.
Because they were all struck at the Philadelphia mint
The 1970 proof penny, as with all modern proof coins, was struck in the same manner as regular business coins ( those intended for circulation ) except the dies used for proof coins are highly polished to produce the mirror like surface on the coin. Also, the proof coin is struck multiple times to bring out the finest detail of the coins' design whereas business coins are struck only once.
Two quarters, a dime, two nickels, and a penny
Yes, but not just wheat penny's, every US coin made (except modern bullion coins) that does not have a mintmark was struck in Philadelphia.
Before 1982, all US 1 cent coins were copper (except steel cents made in WW 2) and a very rare 1974 aluminum penny. After 1982, US 1 cent coins are copper plated zinc. What about 1982- they had both that year? Weigh your coin- if it weighs 3.11 grams, it is copper. If it is 2.5 grams, it is plated zinc.
Two dimes, five nickels, and one penny.
Neither. Since 1992, all British 1 Penny and 2 Pence coins have been made from steel with copper plating. This is an international trend to reduce the cost of manufacturing low denomination coins.
There are thousands of coins in the US, but if you mean circulation coins, there is the penny, nickel, dime, quarter, half dollar, Native American dollar, and presidential dollar.
Indian Head cents from 1859 to 1864 weigh 4.67 grams and are thicker than all other Indian Head coins dated after 1864. Near the end of 1864 the weight change to 3.11 grams.The thicker coins are made of Copper Nickel and the thinner coins are made from Bronze
The non-magnetic pre-1992 'Bronze' Penny and Two Pence coins are made of copper, tin and zinc. British 1 Penny and 2 Pence coins were made from copper-plated steel from 1992 and can all be attracted to a magnet, although the coins themselves are not magnetic.
