It happens all the time - might have gotten oil on it or was in the ground for a while. I see them pretty often while roll searching.
I was at the car wash once. Laying next to a trash bin was a plastic Solo cup full of change and dried up soda. Being the mizerly sort that I am, I took it home and cleaned the change up and spent it. All the cents, new and old that were in that dried up brick of coins looked like this.
Just a heads up, yours is brown from circulation. This one came out of a roll of 09's in 2009. So, it is possible for 1 coin out of a hundred or more to tone. The rest of the cents looked like this.
Thanks Guys, it was just really odd to see a 2 year old cent look like that... I may have seen one, but just don't remember....Tough to get old
The 100% copper layer on the outside of the cent will tone ( corrode) if you live in a moist environment very quickly. The previous 95% copper cent much slower. Jim
I know but that’s partly why it toned so fast. It was obviously exposed to abnormal conditions as well.
It was obviously exposed to abnormal conditions as well.....Well then, it seems like me and that coin have something in common Thanks Collecting Nut !
