1984 P Dime With Errors?

I cam across this dime a while ago and put it away. I was going through some of my jars of coins when I cam across it again. It has many odd places on it. First of all, it has a raised area in front of the top of the forehead on the obverse. It also has a raised area under his nose and under his neck above the date on the obverse. It looks like doubling on the "LIB" of LIBERTY and also on the "IN" and "W" in the IN GOD WE TRUST area. On the reverse, it looks thick in the "RIB" of E Pluribus Unum. On the top left of the coin, the reeding is showing on the edge. Any information you could give me would be greatly appreciated. I have tried searching the net but have come up short. Thanks for your time.
