Kim Brown New Member United States 20 Posts	Posted 10/23/2015 2:11 pm What causes this coin to have this coloration? The dark grayish color is uniform and covers the entire coin.Being a newbie I though maybe a proof, but had read some time ago any color deviation would be on the fields of th coin. Thanks for any info! Report this Post to the Staff

Many different thing cause copper coins to color different ways. Oil on our hands, chemicals they may have been exposed to, if they were lost in the ground, and then found by metal detector. I have seen dozens of color compositions of coins so it is hard to say. Report this Post to the Staff

vermilk Valued Member United States 50 Posts	Posted 10/23/2015 4:16 pm Kim, being a newbie myself, I asked the question - "How do I know I have a proof?". https://goccf.com/t/243481 Check out the link above for lots of good info on determining if you have a proof! Report this Post to the Staff
cwb Pillar of the Community United States 3463 Posts	Posted 10/23/2015 5:37 pm Many newer collectors think "Proof" is a grade of coin. It is not a grade but a completely different die is used to mint them. There are business strikes, issued for general circulation, and proof strikes sold by the mint to collectors. It is possible to find proof coins in circulation (I have found them myself). A proof coin that has been in circulation is considered damaged and known as an Impaired Proof.

Mayflower2020 Pillar of the Community United States 624 Posts	Posted 10/24/2015 12:56 am I am always learning something here. I had not heard of an Impared Proof. Makes sense. I just thought they were lowere graded proofs. Was not aware of the name. Thanks cwb! Report this Post to the Staff
