Welcome to CT. Sorry to be that guy, but this is not a doubled die. It is a form of machine doubling, which is very common and does not carry a premium. It is also not a copper cent, as those ended in 1982, but keep searching, you'll find something eventually!
Welcome to CT Kang. As mentioned by @CaptainMac it appears to be just common worn die mint, along with it being plated in copper, which has its own set of problems. As a suggestion to new members, I usually post this. For the best results, you should post "in focus," FULL IMAGE photos (after you upload your photo, two buttons appear: Thumbnail and Full Image, click Full Image and your photo appears full size on your post and are easily enlarged by clicking on it). Photograph coins on neutral backgrounds like black, grey, or white. Crop out superfluous background so just the coin shows (you can use https://www.remove.bg for free), and post photos with correct orientation so members don't have to turn their computer in some awkward fashion to view it properly. While it isn’t always necessary, it is nice to show both the obverse and reverse, even if your question is just about one side. Members can often give more valuable information having both sides to evaluate. Add close ups of areas you have questions about and make your questions as definitive as possible so we know what you are asking for. And try to have the best lighting possible to show the most favorable photo of the coin. Hope this helps in the future. Good luck. Hope it helps.
@Kang131 Certainly appreciate your enthusiasm but I would suggest you visit www.doubleddie.com for some serious information on doubled dies. The site explains what is and what is not true doubling along with plenty of other info on coins and the minting process. Hang in there. Errors and varieties are a lot of fun but we don't need to see you disappointed over and over again.
It’s MD or machine doubling and it’s very common. It’s also on all denominations and carries no extra premium. Welcome to CT.
With some people wanting as complete a collection as possible, I'm wondering how many here consider having both A & B positions necessary in having a complete Presidential coin series.
