Is This An Error?

There is something extra on the penny beside the "u" in united. Its a raised area.. Also, kind of bubble areas through "one cent."? you may have to pay close attention to it. my pics arent all that great..Also the same raised dots on the top area of the building and middle part of building. doesn't look like damage after mint to me, seeing is how it still holds the same color and is not gouged out, its more raised, like a bubble almost? Anyone have any feedback? Am I just trippin? lol :)
