Found a 1979 d with absolutely no hint of copper. Any ideas? Working on pics.

  Biokemist6, I don't have a scale. Most that I looked at are over $200 and I just don't have the money right now. |

$200? You can get a decent pocket scale for less than $20. Looking at the images, it appears to be a normal fully struck Lincoln so it is not struck on a dime planchet. Without providing a weight, the best explanation is that the coin has been plated.

If you continue to collect coins you will need a pocket scale eventually. Browse this link:- http://dx.com/s/pocket+scalesBought one myself through this company and it works fine. |

You can remove the copper plating from your US pennies - perhaps someone did that.

If it was a Zincoln, I believe the Zn would melt before the Cu. I vote for plated unless it is a mule, but looks the same size as a cent.

Gosh it is pre-zinc times. Interesting. I say it is plated, and probably zinc plated.
And you can chemically burn away the copper leaving just the zinc behind. Someone does it on Youtube - I havent seen it done to a UK penny yet.
