Please post a new and more specific question.
The US didn't mint nickels until 1866 and the first coins to be struck in a copper-nickel alloy were Flying Eagle cents in 1856.
Cupronickel or copper-nickel or "cupernickel" is an alloy of copper that contains nickel and strengthening elements, such as iron and manganese.
Nickel cannot replace copper in copper II sulfate because nickel is higher in the electromotive series than copper.
nickel and copper are elements that can be magnetized
No - copper is a better conductor than nickel.
copper has more protons than nickel
Please rephrase question.
The coin is 75% copper and 25% nickel, so the coin is likely face value the date is still in circulation.
If you have a US nickel, it is either coated with copper or has changed color due to exposure to some chemical and has no special value. If it is a 1942 Canadian nickel, it varies from $.40 to $1.75 in circulated conditions, $3 and up in uncirculated grades. The material is called "tombac" and is an alloy of copper and zinc.
Sterling silver is 92.5% silver with 7.5% copper and no nickel.
I have a silver dollar of 1853 I think it is copper or bronze that was in circulation for wear, someone could help me know how much it cost? Thank you. my e-mail is superkin74@hotmail.com
This is not a Mint error, it's a novelty coin that has no collectible value.
It is made of copper and nickel. A 1949 NICKEL is made from copper & nickel.
No matter what denomination it is, if found in circulation it's face value.
Copper-nickel. If circulated, it has no particular special value.
The first 5-cent US nickel was made in 1866, the 3-cent nickel in 1865, and the copper-nickel flying eagle 1-cent in 1856.
The melt value of something is the value of the metal itself. For example, a 1964 nickel has a melt value of 5 cents because 1.8 cents worth of nickel and 2.7 cents of copper.
All US nickels (except for silver war nickels) are 75% copper and 25% nickel, with a present melt value of 4.9 cents.
