I've always wanted an Oregon Trail Half, one of my favorite designs. I can almost guarantee that photo has been edited. GSC is known for that, I bet that coin certainly looks different in hand. Not just the color, they may even be the real color, but there are marks on that coin that aren't being shown in the photos.
No wonder so many of their coins look flawless! How can you tell there are marks on that coin that aren't being shown in the photos?
Based on their feedback the last few years and the people who buy coins from them on the coin forums claiming the coins are not how they are pictured. That coin is nowhere near as flawless as it seems
