simpler version not much
The United States currently has five different types of pennies: the Lincoln Memorial penny, the Lincoln Bicentennial penny, the Shield penny, the Lincoln Union Shield penny, and the Lincoln Wheat penny.
Centimeter is to meter as a penny is to 1$
The density of a penny is higher.
A penny is a penny. You could try "centidollar" (one hundredth of a dollar). Or in the US: a milliJackson (one thousandth of $10 - Andrew Jackson's portrait is on the $10 bill)
One way to make a penny float is by using the surface tension of water. Carefully place the penny on the surface of water in a bowl or cup, making sure it is placed flat. The surface tension of the water will allow the penny to stay afloat.
You may have what's called a "flan", a coin blank that accidentally didn't go through the press to have the normal images struck onto it. If it's a lightweight modern cent blank, it's worth about $1. If it's an older copper blank it's worth $2 if it has a flat edge, $3 if the edge is turned up like the edge on a normal penny.
Yes. Wheat pennies were made 1909-1958. A wheat penny has wheat on the backside.
By far the most valuable Lincoln cent is a 1943-D coin struck in error on a bronze blank instead of a steel blank. As of this writing (2015) it sold for $1.75 million.
If the back of the penny is just blank, this penny can be worth a fortune. Have the penny appraised at a coin dealer.
A new penny blank planchet is worth $1.50.
You could have what's variously called a blank planchet or flan. That means it's a coin blank that accidentally didn't go through the coinage press but was still released to circulation. Given that cents are struck at extremely high speed, the error happens more than you might expect so a cent flan will only sell for about $1.
I also have one with letters from liberty across the face. Thanks
I've seen nickels struck on cent blanks, but not cents struck on nickel blanks -- the blanks are too large for the feeder tubes. I suggest you contact Mike Byers -- an error expert. His website is here : http://mikebyers.com
A copper blank is pretty much without value. There is no way to know if it is actually a penny blank. It could be a punch out waste product from all sorts of equipment manufacturing.
Cent, not penny. Mint mark, not mint. Mis-struck, not misprinted. Now that we're past the terminology, what you have is called an off-center strike. It happens when the blank on which a coin is struck doesn't seat squarely in the press. Cents are struck at extremely high speed so this error happens more often than you might think. It would probably retail for a couple of dollars depending on how much of the image is visible.
These sell regularly at coin shows for a dollar or less.
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.
