A technically perfect picture - but why? As a macro there is no advice to give, your focus is incredible. But other than that, what does it offer of interest? I questioned the pink background, and the grey coin does look good on pink but I bet you could have improved your score half a point simply by putting it on a flag, or something with american colors.
This is technically well executed, but that is it. I am honestly suprised that this wasn't DQ'd due to the literal representation clause...but I'm not a fan of that clause anyway. In the future, utilizing your obvious skill in the technical aspect of photography while employing a more artistic aproach should yield you better results.
Composition: 3, Dead center and flat... not really a creative composition, it's more of a "documentary" (like something you might shoot to give to your insurance company in case of theft).
Technical: 5, The focus seems right on for the bottom 2/3rds of the image, but looks just a little soft on the top 1/3rd. A more dynamic image would have taken advantage of the shallow DOF assosicated with macros and extreme close-ups by keeping the main subject in focus and allowing the rest of the image to blur in order to establish a 3-dimensional look in the image.
Appeal: 5, Hard to rate the appeal ... it's just "there". Again, like a documentary. It doesn't appear to be an image that was meant to show the creative side of the shooter.
Challenge: 5, Nice close-up. A more macro version might have focused in on just a portion of the coin and explored the texture of the metal or the engraved writing.
Overall Calculated Average Score: 5, Not a bad image... It just lacks a reason to want to spend more time looking at it.
sorry to be blunt but in a challenge with 350+ entries i think your shot is uninspiring, dull and boring. imo this is the type of shot you take to see if your lens is working properly.
I do feel that we get coins in a lot of challenges, whether its obsolete, metal and now macro. To get a good score with this subject the image is going to have to be superb.
