When sorting the coins you've found metal detecting, it can be difficult to tell the difference between a US copper penny and a US copper-clad zinc penny. Oftentimes the date can't be read easily (or at all!) due to the condition of the coin, and if the penny was minted in 1982 it's hard to tell since both types were made during that year. Here ...

In most years before 1982, American pennies were 95 percent copper. Then the price of copper went up until you could get $100 worth of pennies at the bank, melt them down, and sell the metal for more than $100. So the government started using a core of cheap zinc with only a thin plating of copper. The fact that pennies are made of two ...

I went to do some business at the local bank and turned in some zinc and got back 10 more dollars to sort thru. It ended up being 75% copper pennies. Wish I could get more bunches like that.

These are all 95% copper pennies - no post '82 copper coated zinc cents here. Right now, it is illegal to melt US cents. I believe this will change, but I never plan to melt them anyway. As the coins are now, in addition to having the metal value, they also have collector value since they are currency. It's just like the junk pre 1964 silver ...

There are also little machines that either use magnets or send a current through to sort the pennies. A good way to find the difference between the weight for your scale is to weigh a new penny and then way a 1981 or prior penny. That way you will have an idea on what the Zinc and Copper differences are with weight.

This is a 1969 copper penny reacting with concentrated nitric acid. The copper is getting oxidized to form copper(II) nitrate (the blue compound) while the nitric acid is getting reduced to form nitrogen dioxide gas (the brown gas).

Like their UK counterparts, Aussie pre-decimal pennies were huge. All are now coated with a layer of copper oxide that is easily removed (coin collectors, please don't freak out) to reveal the beautiful copper surface beneath, and then converted here into a 'silver' penny then into a 'gold' penny. It's a neat well-known chemistry demo that ...

Many investors who buy gold and silver bullion coins and coin collectors who study coins, have probably never considered collecting copper pennies to make a worthwhile profit. You've probably heard "a penny saved is a penny earned," because the lowly penny is worth one cent. While most pennies are worth a meager face value, did you know that ...

Of interest to copper investors. How much does a penny weigh? It depends on the penny. Some pennies are copper, some zinc, and for a short while they were made of steel. Lincoln cents made prior to the later part of 1982 were made of 95% copper. After the first part of 1982, they began to make zinc pennies. The weights vary, as copper is more ...

Two different pennies are compared in their reaction with concentrated hydrochloric acid. A pre 1982 penny is mostly copper and doesn't react with HCl. A newer penny contains zinc coated with a thin layer of copper. When some of the surface copper is removed, the exposed zinc reacts with the HCl yielding hydrogen gas and ZnCl2.

To find the percent composition (by mass) for each element in CuSO4 we need to determine the molar mass for each element and for the entire CuSO4 compound. We’ll use the following formula for percent composition by mass: Percent Composition by Mass = (Molar Mass of Element x Number of that Element)/ Molar Mass of Compound In this video I’m ...
