Question
I just received a penny in change which other that the material, looks like any regular 1997 Denver mint penny.  The material, however, looks like steel or some similar material.  It is not a wafer type material like dimes, or even solid material like a nickel.  Was wondering what it could be.  I tried a small scratch test on the rim to see if it was somehow coated, but no.  Under a magnifying glass all lettering looks normal and the date is 1997D.
I thought steel pennies were only from the 40's? Thanks for any info.

Hi Bob:

Thanks for your question. You could have a zinc cent that was struck with the copper plating missing. The U.S. Mint vended out the making and plating of the cent blanks to an outside firm. It is possible that your coin missed getting the copper plating process, was sent to the Mint, and was struck. This error would likely have a retail value of between $100 and $250, depending on strike and condition.

This "error" can be man made after it left the mint. The coating can be removed. Your coin should be looked at by a professional. Altered coins would have no added numismatic value.

Here are two sites to check actual error values:

You may want to check US coins and currency listings under errors on eBay from time to time to see if your coin is listed what this type of item may bring.

If you live close to a local shop, they should offer an opinion as to the value at no charge. Always try and get at least two opinions and try and deal with PNG dealers if possible. If you should decide to sell your items to a dealer, remember they will offer about 50% to 60% of the retail value. Here's a link to find one in your area: http://www.pngdealers.com/dealersearch.php
