your focus is fine on the photos. you need to stop using overhead lighting as its obscuring the surfaces and we are unable to determine how much, if any, wear there is plus if the luster is broken. they can be a little sharper as well. whether you are using a phone or camera it needs to be stabilized either with a tripod or place books on either side of the coin that you can set the phone/camera on so you don't have to hold it. does that make sense?
