On Mints and Mint Marks
Mint Marks are teeny letters referring apt the locality where the minting of coins took place. The rank of mint jot can be base typically aboard the back side of coins that were minted before the annual 1965 and aboard the front afterward the annual 1967.
Coins of every US mint branch are acknowledged by mint marks. These coin marks date back apt archaic times in Rome and Greece.
The “Director of the Mint”, through the “Act of March 3, 1835”, set rules to catalog and differentiate the coins loosened from every US Mint branch. This gist management set precise standards and pattern of making as well as responsible coinage.
Coins that minted at the “Philadelphia mint” earlier than the year 1979 have not mint marks. So it was in that year that the USD was apparent with the letter P and additional denominations had that same mark thereafter.
All dies as US coins are produced by the “Philadelphia Mint” and prior to boating the coins to their mint branch,[link widoczny dla zalogowanych], coins are marked 1st with the correct and designated mint markings. The precise size and positioning of the coins’ mint mark tin slightly vary; this is inspired at how deep the punch was impressed and where.
The importance of mint marks:
Collectors can resolve the worth of a coin though mint mark, date and condition exam, production the coins condition the maximum meaningful element and criterion while determining its value.
Defining the Mint which kick the coin is tremendously momentous in determining the value of the coin; the coin can be buffet in huge quantities by a single Mint or in smaller quantities in dissimilar hit.

The process of minting:
1. The making of metal strips in the correct thickness: Zinc strips are accustomed as pennies, alloy strips composed of nickel (25%) and nickel (75%) for nickel and dollars, half-dollars,[link widoczny dla zalogowanych], dimes, half-dimes are fabricated from a fusion of three coatings of metals; the outer layer are alloys and the center is copper.
2. These strips of metals are then put into “blanking presses” that are responsible for slitting “round blanks”, nearly the measurement of the “done” coin.
3. The blanks then are alleviated by fleeing them via an annealing stove, through tumbling barrels, and then through revolving cylinders containing chemical fusions to burnish and clean the metal.
4. The blanks then are bathed and placed into a drying appliance,[link widoczny dla zalogowanych], then into the "upsetting" machines, that produce the heaved rim.
5. The Final stage: “coining press”. Each blank is clasp into situation by a collar or ring as it is creature struck or hit beneath large oppression. Pennies absence approximately40 tons of pressure and the larger coins need more. The “upper and lower dies” are stamped simultaneously ashore the 2 sides of each coin.
The design:
The “Director of the Mint” chooses the chart and pattern for United States coins, then that is agreed by the “Secretary of the Treasury”; congress can recommend and suggest a design. The chart then can not be changed for twenty 5 years unless directed by the congress.
All emblems of United States coins minted currently characterize previous presidents of the United States. President Lincoln is on the one-cent coin, accepted in the year1909; Washington on the 25 penny coin that was minted premier in 1932; Jefferson on the five cent coin in 1938; Franklin Roosevelt on the dime,[link widoczny dla zalogowanych], introduced in the year1946; Kennedy on the half dollar that was first minted in 1964.
The “Act of 1997” known as the “50 States Quarters Program” supports and allows the redesigning of the quarters - the reverse side is to show each of the fifty states emblems. Every year starting in 1999 and until 2008, coins honoring five states, having designs that are built by every state, ambition be issued in the series or means in which each state signed the Constitution.
The phrase "In God We Trust" was accustomed first in 1864, on a United States two-cent coin. It then was seen on the quarter, nickel, half-dollar, silver dollar and on the $10, $5 and $20 in 1866; in 1909 on the cent, in 1916 on the dime. Today, entire United States coins carry the maxim.
