I Feel Like Ancient Coin's Coins Could Be Larger

I didn't feel like I had a major problem picking them up but I felt like I had to focus on it more than necessary. For example, they could be easy to miss if I moved the camera to look at another lane or didn't hear them drop. I think a little work could be done to make them stand out more. They seem a bit small and without much visuals to grab your attention to them.
