CONECA - The Club for Error Coin Collectors

1955 Doubled Die Lincoln Penny Searching pocket change for error coins is more popular than ever, with the economy the way it is these days. There are doubled die pennies worth hundreds, even thousands of dollars being found in circulation right now, including the 1972 and 1995 doubled die cents. You can find Presidential dollars with various edge lettering mistakes. And if peering through a magnifier isn't your cup of tea, try searching rolls of half dollars for the 40% silver halves minted between 1965 and 1970, which people are spending because most folks thought the silver in U.S. coins stopped in 1964. My article about the Top 10 Most Valuable Coins Found in Pocket Change is consistently one of the most popular pages on my Web site. That's why I wanted to tell you about a coin collectors' club devoted exclusively to error coins and die varieties: CONECA.

CONECA stands for the Combined Organizations of Numismatic Error Collectors of America, and it has a long and distinguished track record of service to the error-varieties (E-V) coin collecting hobby. CONECA publishes a magazine called Errorscope and maintains a Web site with comprehensive Variety Master Listings for nearly all 20th Century coin types, but best of all, CONECA Webmaster Ken Potter maintains a blog on the CONECA home page depicting the latest error coin finds and news relating to the E-V hobby. Learn more about this club especially for error and variety coin collectors, and find links to their resources and information about how to join in CONECA - The Club for Error Coin Collectors.

By the way, they have a really nice website at http://www.conecaonline.org

It’s worth pointing out that their website is conecaONLINE.org because people might naturally think its at coneca.org and that website is owned by some squatters.

I found a 1965 penny that looks normal, except it has extra metal on the edges. I will describe it as having nipples. Does that happen much?

Is a 1963 copper penny printed on one side only worth anything? It shows only the top with Lincoln. The back is totally blank.
