The most probable cause is that the coin was struck at the mint on a blank (planchet) that was not of the proper thickness. This isn't a most uncommon event even though the mint does a good job with quality control. That means some coins slip through that are "non-standard" and have some collectiblity and some worth beyond face value.
What country are you talking about? New U.S. cents are not magnetic; they're made of copper-plated zinc. The only magnetic U.S. cents were the steel ones minted during 1943 so copper could be used in ammunition. New Canadian cents and British pennies are magnetic because they're made of copper-plated steel. The price of copper went up so much that it cost more than a penny to mint the coins, so the governments were losing money on each one. They switched to steel as a cheaper alternative.
No. Since 1982, US cents have been made of copper-plated zinc. If the copper is removed by wear or some agent like acid, the underlying zinc has a silvery appearance that some people confuse with aluminum. In 1974 the US Mint struck experimental cents in aluminum but they were too lightweight to be practical - they could actually blow away in a stiff breeze. Most of these coins were destroyed and it's illegal to own one privately. However there are persistent rumors that some, or possibly many, were secretly held back from being melted. So far none have surfaced though.
Assuming a quart is equivalent to 946 pennies in volume, this would be the maximum amount of pennies you could fit into a piggy bank with a quart capacity.
Silver is not used in pennies due to its higher cost compared to other metals like copper and zinc. In the past, pennies were made of mostly copper, but today's pennies are mainly composed of zinc with a thin copper coating. Using silver would make the production of pennies more expensive and would not be cost-effective.
A U.S. nickel weighs approximately 5 grams, so you could use around 3/5th of a nickel to represent an object that weighs 3 grams.
US Pennies were made of 95% copper (with the exception of the 1943 steel cent) from 1864-1982. Midway through 1982, the cent switched to copper plated zinc. So any penny dated 1983-present is just copper plated zinc. However a coin dated 1982 could either be 95% copper or copper plated zinc. A copper coin should weigh about 3.11 grams while the zinc pennies are lighter at about 2.5 grams.
The US does not made tin or silver pennies. However it could be plated with tin or silver. Either way they are only worth one cent.
It would depend on how many pennies they had!
One million pennies is equivalent to $10,000, as there are 100 pennies in a dollar. Since a loonie is worth $1, you could have 10,000 loonies for 1 million pennies.
It could indicate KaraT Plated, meaning that the necklace is gold plated.
Indian Head cents were not made until 1859 and did not exist in the 1820's. All US cents at that time were Large cents, so they could not have been used together.
You could have: 3 quarters; 3 pennies 14 nickels; 3 pennies 7 dimes; 3 pennies

Pennies minted in the United States cents from mid-1982 to the present are copper-plated with zinc inside. By weight, the zinc core comprises 97.5% of the coins' metal. There were some 2009 bicentennial cents minted specifically for collectors that were made from 95 percent copper and 5 percent tin and zinc,
There are approximately 181 pennies in a pound, so 10 pounds of pennies would be approximately 1,810 pennies. In terms of value, each penny is worth $0.01, so 10 pounds of pennies would be worth $18.10.
There could be several reasons. 1. Some may be in contact with water. 2. Some may be scratched. 3. Coinage metals are sometimes changed. Pre-1992 British decimal pennies were bronze but now they are copper plated steel. 4. Some may be in contact with different metals, forming a couple which can sometimes accelerate corrosion.
