This coin looks a bit mangled, as if a car ran over it. It's really a copper cent struck on a silver dime. And no, that doesn't make it worth a nickel.
The excess of metal at the top of the Lincoln cent is called a cud. It is caused when a piece breaks from the die face and leaving a hole into which the metal flows as the coin is struck.
Spot the doubled die on an otherwise common dollar coin. Not all of them can be easily seen with the naked eye. In this case it is at the intersection of the Statue of Liberty's arm and the spike from her crown. An enlarged photograph inside will reveal it.
It takes a keen eye to spot them, but errors on coins produced by the U.S. Mint occur every year, and they can be worth money to coin collectors. "Strike It Rich with Pocket Change" is THE book that shows clear, concise photos of those errors and tells what those coins are worth in today's market.
What an unusual book this was. Although this is not something I would normally read it has been quite interesting. Until I got this book I had no idea that you could make money from coins with errors on them.
My 10 year old devoured this book! My 7 year old has had a lot of fun with it as well. Apparently this topic is fascinating to children. Both kids have gone through every coin we have in the house and sure enough they found two of the ones mentioned in this book. It has fun to read something with the kids and talk with them about it.
As a coin collector, I found this book and decided to try it. There was definitely some varieties that I had not heard of or seen, but most of this book was about double die and mintmark errors, which. I suppose could be useful, but if you are roll hunting you should know the spots to check for doubling. Also, a good chunk or errors listed are worth $15 or less. However, I would absolutley recommend for a newer collector.
