I am not sure that, that isn't damage. Here are the Rpm's for the date. It doesn't seem to match any of them. http://varietyvista.com/05 JN RPMs/RPMs 1952D.htm
Can't be "looks more like". Needs to match exactly. You've been posting questions for a little while now. I would strongly recommend going to the variety vista site and read about how dies and coins are made. The more you know about the process, the easier it will be for you to spot real errors or know when it's simple damage. As you learn you'll understand why a D mm can't be a Q.
I know that it is not a Q. I said it looks like a Q. The bottom mark on the Q is to the right and the bottom mark on the D is to the left. Thanks
