i would think not a bad deal and like stated early defiantly capable of proffesional quality shots. I just looked at bhphoto.com for a macro for myself and found a canon for $265 that should do the trick, you can also get some a little cheaper but I really wouldn't go any lower than $200. might even be able to get a good used one on
ebay, bhphoto.com also has a used section didn't get a chance to look there yet. you probably should also get a tripod and use the self timmer on the camera, now don't forget you will be able to use this camera for alot of other things to, and take care it and it will last you a very long time. I don't know much (next to nothing about coins) but I do know a thing or to about photography
