you also (in addition to what has been said above) want to be looking straight down at the coin instead of at an angle. I have taken pictures of my album with the coins in the album ( as a matter of fact all the shots of the album in my signature were taken with the coin in the album) but its better to take the slides out so there is no glare from the light source. You also seem to be really shaky so some type of tripod or something may do wonders as well. I do like a sniper when I hold my camera in hand I will take a deep breath and right before I start to breathe out I take the shot. I always have to make sure my arms are steady on something also and try to hold the camera as steady as possible. These things may help a lot with your pictures
