OK. Start here:
https://goccf.com/t/29441Everything I talk about concerning setup is true for you as well. Your camera does not have manual controls, so the settings discussions aren't relevant, but everything else is exactly what I'd suggest for your specific camera. Macro mode on your camera is the "down" arrow on the 4-way selector - the picture of a flower.
Follow my suggestions for setup - firm mount for the camera, camera and coin parallel, delayed shutter (on your camera that's the left arrow). Start maybe 6" from the same coin and see what we get.
