Animation frames invisible

Okay so I’m trying to animate a coin and one of the keyframes is just not visible. All of the settings are the same for all the frames, but that one frame is still not working. Any way to fix this?

I’ve come across the same problem in 2D games on multiple sprites. The solution that worked for me is to assign more than 1 sorting layer and configure them correctly. If you have a background, assign it to a new sorting layer and configure it to be first - this way Unity won’t be confused if the sprite is in front of or behind the background.
