OK, I'll put in the other of my two cents...
It really is a nice coin ! Certainly wish I was digging things like that !
...IF your camera has the macro function, use that.
If not, take the pic, load to PC, then CROP the photo, as opposed to resizing which just reduces quality of the overall pic.
Take your pics with the object on a piece of paper rather than the carpet.
Light gray, a neutral color is best... anything is better than a dark color which wil just make a big jpg file.
Outside sun-lighting is also best.
Have fun !
