This 1986 D cent weighs 2.46. It has a minting line strike above "IGWT". I'm curious if this is a double die or proof strike? Any help would be appreciated.
Not a double die or proof. Could be a die crack, but I'll let the people who know more about errors decide. May just be damage.
Proof coins are usually produced as collectors items, and they have a mirror like background to highlight the image on the coin. An example of a reverse proof coin of mine: 2014 Canada Maple Leaf PF-70 Reverse by Wheatmaster101 posted Mar 25, 2015 at 8:20 PM 2014 Canada Maple Leaf PF-70 by Wheatmaster101 posted Mar 25, 2015 at 8:20 PM On normal proof coins, the background or non-image part of the coin is mirror like.
Your Cent is minted on a Copper Plated Zinc Planchet. Die Deterioration causes that effect. Nothing at all to do with a Doubled Die
I'm learning what to look out to find. What about this coin? https://www.cointalk.com/threads/1988-lincoln-penny.312132/
All 1986 Proof coins were issued by San Francisco and have the "S" mm. You have a business strike from the Denver mint
