Well, its a short length of wood board. There are 18 faces and as Scouting Ninja said, you shouldn't model those bevels for game use. Mobile games take a standard 6-faced stretched cube ( = cuboid) as well as PC games but PC could use a normal map as well if the board is viewed close up.
It's not very elaborate and definitely not something people would buy as they could just use a cuboid with a simple texture for similar result even if they didn't know first thing about 3D modeling.
It's good practice for texturing and modeling but I'm afraid you're going to work harder if you want to make some money on the competitive 3D model market. That being said, it's still a viable 3D model that you created so keep on modeling and move on to more challenging shapes
