The coin is made from a alloy of silver, copper and manganese
This coin appears to be minted on a delaminated planchet. You should search for a coin error dealer on the Internet. If it truly is SILVER (if it has a S mint mark), instead of the normal nickel finish (P or D mint marks), it is probably worth quite a lot of money. The only SILVER state quarters are Proof, and they go thru many inspections before leaving the Mint.
Original Answer:If you mean "lustrous, metallic, and silvery with a gold tinge" it might be NickelNot Manganes, though used in steel making, it is not ferromagneticNickel (not Nickle oxide) or CobaltA ferromagnetic alloy material is a transition metal-metalloid alloy, made from about 80% transition metal (usually Fe, Co, or Ni) and a metalloid component (B, C, Si, P, or Al)Added:Antiferromagnetic materials occur commonly among transition metal compounds, especially oxides. Better known examples include hematite, metals such as chromium, alloys such as iron manganese (FeMn), and oxides such as nickel oxide (NiO).
5¢. Please check your pocket change. Billions of nickels were minted* in 1964 to help alleviate coin shortages during the changeover from silver to cupronickel in higher denominations. That date remains one of the most common in circulation prior to coins minted in the 1990s and 2000s. (*) FWIW #1, coins are said to be minted or struck. "Stamped" usually refers to industrial items like spoons and fenders. FWIW #2, nickels struck at Philadelphia in 1964 did not have a P mint mark. That letter has been used on nickels only from mid-1942 to 1945, and again from 1980 to the present.
Brass is an alloy of copper with tin (sometimes added Al, Mn, P, As, Si).From brass are made cartridge cases, musical instruments, sculptures, bells, handicrafts and many others.
In the Earth's outer core, which is composed of molten iron and nickel, seismic waves (P and S waves) are not able to travel through it due to its liquid state. This causes a shadow zone on the opposite side of the Earth from a seismic event, where P waves are completely deflected and S waves are not detected.
No such coin exists. All 1942-D nickels are made out of the standard 75% copper 25% nickel. Only 1942-S and 1942-P nickels were struck out of the "war nickel" alloy of 35% silver. A 1942-D nickel is worth about 7 cents if circulated and a couple of bucks if in better shape.
The large "P" above the dome means it's a "war nickel" that is struck in 35% silver. The nickel was removed for the war effort and silver was used as a replacement, this was done from 1942 - 1945. Because it has a small amount of silver the value is about $1.00. NOTE: The 1942 war nickel is the first US coin to ever use a "P" Mintmark.
That's a silver war nickel from WWII, which contains 35% silver. It's worth about $2.
Because of the urgent need for nickel metal during WWII, virtually all of which must be imported into the United States, the nickel or 5 cent piece was changed from 75% copper and 25% nickel to 35% silver, 9% manganese, remainder copper, in roughly October, 1942. All nickels for 1943, 1944 and 1945 were made from this alloy. Obviously, some 1942 nickles were made from the original alloy, which contains no silver, as explained above. They can be easily differentiated because the mint mark moved to above the dome of Monticello with the change, on the reverse side of the coin and, for the first time in U. S. coinage history, a "P" was added for those coins minted in Philadelphia. The copper/nickel 1942 nickels show the mint mark in the same location as the other Jefferson nickels minted since 1938 and after 1945.
I assume you are referring to the so-called "war nickels" and not half-dimes. From 1866 to 1942 all US nickels were made of copper-nickel alloy. Nickel was a strategic metal during WW2, so to reduce its use in coinage the composition of the 5-cent piece was changed in mid-1942 from to an alloy of silver, copper, and manganese. Only about 1/3 of the alloy was silver so technically there has never been a "silver nickel".Some 1942 nickels were struck in the old composition and some in the silver alloy. From 1943 to 1945 the silver alloy was used for all nickels. Normal composition was resumed at the start of 1946 and continues to today.The silver alloy coins bear a large mint mark above Monticello's dome, instead of a small mark to the side. The letter "P" was used for Philadelphia issues for the first time on any US coin.When new, the coins looked very similar to their copper-nickel cousins, unlike the zinc-coated steel cents issued in 1943 that were often confused with dimes. However after a small amount of wear the silver and manganese components tarnished severely and the coins turned an unpleasant dark gray."Nickle"Be careful of this common misspelling. The metal and the coin are NICKEL. A "nickle" is actually a small European bird (!)
Both silver and nickel 5-cent pieces were made in 1942. The ones that contain silver have a large P or S mint mark over the dome of Monticello. Please post new question with the location of the letters you see.
It looks like a normal Jefferson nickel but is dated 1942-1945 and it also has a large mintmark (P, D or S) on the reverse above the Monticello. Keep in mind that a 1942 coin without a large mintmark is NOT silver but is the standard alloy. As for visual differences, in mint state they look identical in color, but circulated examples often have a green-ish tint to them.
The years 1942-1945 contained 35% silver. Not all 1942's though. If there is a large P, D, or S over the monticello on the reverse of the coin then it contains silver.
In WWII, The United States had to use 56% Copper, 35% Silver, and 9% Manganese. The dates for these 35% silver nickels are 1942(P,S) (NOT D), 1943(P,D,S), 1944(P,D,S), and 1945(P,D,S). The mint marks on these coins are located above the dome of Monticello. Contrary to popular misunderstanding, these are the only US nickels that ever contained silver. The rest are all made of an alloy of 25% nickel and 75% copper.
It depends. If there is no large mintmark over the Monticello it is copper-nickel and contains absolutely NO silver. If there is a large mintmark over the Monticello (P, D or S) it is 35% silver and contains .0563 troy ounces of silver.
Nickel was needed for the war effort during World War II. In order to meet the needs of the military, nickel was not used for the production of the Jefferson Nickel. Beginning in 1942, the composition of the nickel coin was changed from the original alloy of 75% copper and 25% nickel to a new alloy which consisted of 56% copper, 35% silver and 9% manganese. In order to show which coins had this new alloy the mint mark which had been located just to the right of Monticello [the building on the back of the Jefferson nickel] was moved to a new position just above the building. Additionally, the size of the mint mark was greatly increased. Also, for the first time in the history of the US Mint, the mint at Philadelphia used a mint mark on one of the coins produced there, the letter "P". Denver continued to use the letter "D" and San Francisco continued to use the letter "S". Since the alloy of the nickel was changed during the mintage year, there are 1942 nickels of the former alloy and there are 1942 nickels of the new alloy. In 1946 the composition of the nickel was again changed and the original alloy of 75% copper and 25% nickel was used and continues to be used today.
That is known as a "war nickel" to save nickel for the war effort, the US government replaced some of the nickel in the nickel with silver. At the time of writing the silver content in them is around $1.70. The reason for the mintmark over the Monticello was that the idea was that people would know they contained silver.
