Hey Adrean You'll have to do better in order for us to help you. You need a good title and your Pics didn't come through.
Sometimes a short flop in a subway station toliet can make a difference Many things can effect the color...laying in a hot car,or wiindow with direct sun light.
Adrean - welcome to CT! Here is an inexpensive setup that will improve your picture taking. Taking pictures is half the fun...many members here are very good at it. It can be frustrating too, but hopefully you will see it as a fun challenge. Good luck!
It's due to the way they were stored. They won't stay minty bright if you keep them in a reactive atmosphere.....
@Adrean B Westling FYI - The General Discussion forum you just posted your thread in is for Non Coin related stuff. Such as posting your rock collection or asking "What's your favorite cereal?" Next time use Coin Chat or US Coins. Any coin you think might have a Mint Error or Variety goes in the Error Coins forum
Granola, but most things with oats. I do occasionally eat the bowl of cereal while looking at coins or browsing CT. Close enough?
For the glass, I used a piece from a broken picture frame. Repurposed it for good use. If you note, those photos were taken with an old iPhone 5. Cameras have improved, but I keep this set up all the time for quick shots. When I need a better shot, I'll use my newer iPhone and/or the Amscope for closeups.
Welcome to CT Adrean. As mentioned, from your photos, it simply appears to be toning. Exposure to many, many different type of items will cause the skin of the coin to start changing. Some like heavy toning, while others prefer bright white coins. This is something I put together a while back, for new members. It may be helpful, but if not, I apologize. For new coin collectors Being new to this site, we have no idea how knowledgeable you are in coin collecting (numismatics) so it's hard to judge how much information to give you. We at CT try to help new members as much as possible (for free), so without knowing your skill level, let me give you some info. If you just found an odd looking coin and wanted to find out if it is an error, or worth more than face value, we can do that. There are a ton of good online sites that can answer a number of your questions, so do some reading and self-education. I've listed some at the bottom. Photo info for new members to CT I belabor the point of photographs to most new members so will give you my standard spiel. 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.
