New coin mesh and coloring

I've decided to add a mesh to my coin by using one that was given to me. I then created a color by creating a new material and using a base color of gold. Following that I began to adjust the emissive color, roughness, and metallic material. I did the same thing with the object that decreases my health only I made it red. Below is the code I used to make this all happen and the final result.

This is for the coloring of the coins which includes the roughness, metallic state, and UV detail

This is for the object that lowers the players health
