[QUOTE="John Burgess, post: 8064890, member: 105098"]Hi Ragu, your question really would need a picture of the coin in order to determine what happened. there were no "matte finish" cents struck in 2013 and "satin finish" cents ended in 2010. in all likelihood the reason will be one of a few causes for the appearance. 1. toning, copper is really reactive. 2. zinc particles under the copper plating, this will give a bumpy appearance. 3. roller lines, when the zinc is rolled out to proper thickness, the rolles can get grit or jam and gouge the zinc before it's plated, and then the strike doesn't remove the lines either. 4. possible a struck through slight overgreasing, sometimes this will make the coin look hazy or "fogged" like a matte or satin finish and all details are present. it could be a lot of things, but no way to tell unless a picture is provided. one thing though, the mint didn't make any cents that were matte or satin finish in 2013. like this, it's from an old thread, but it's the same coins, same date and MM, but they look different. both found at the end of 2013, judging by in front of the ear and top of lincolns hair, and bottom of the bust, it's MAYBE even the same obverse die at different points of the dies life, my opinion the coins visual difference is due to the die deterioration at different points in the die life, they reflect light differently due to die wear, and possibly toning playing a factor here also. [ATTACH=full]1398130[/ATTACH] picture would be useful for me to go any further on your cent and what might have caused what you are seeing, we'd need to see what you're looking at. I pull this picture of roller lines out whenever I can, :) This is one of my favorite worthless (valueless) coins in my collection. this is actually a date where the mint was making satin finish coins for mint sets, but this is not from a mint set, just a business strike. looks very different from other 2005s.
