I had a blast creating this!
My workflow for this was rather basic, at first I created all the assets as highpoly models.
At this point I started staging the whole scene, while creating the final render camera.
Next I created the lowpoly models (25.000 tris) and three different texture sets. One for the backdrop with the badge, the second for the board with the coins, and the third for all the assets in the corners.
While texturing and creating the effects I always rendered the scene in marmoset to get the lighting, shading right.
I hope you guys like it and if you have any questions just ask in the comments
