I got a coin I found in my grandfathers collection and it has a lump that sticks out on both sides. It doesn't sit flat. Its very odd how this could have happened. Let me know you think :)
This is post mint damage from heat. When heat is applied to a clad coin it causes trapped gases between the layers to expand and this is the result. Nothing in the minting process would cause this. Also WELCOME to the forum.
