They are made for people who buy a camera with interchangeable lenses and then try to get one lens that does everything poorly. I will never understand this desire. Generally the longer a zoom range is, the more it must compromise at one end or another. Do-all zooms focus closely but do not have the other corrections required for best work at close distances. Macro lenses are made to give their best results at closer focusing distances and provide sharp images out to the corners with a flat field of focus. They are great for shooting a dollar bill. Coins, however, are round and do not use the corners of the lens so you can forgive a lens that has lesser performance in corners or focuses at a slightly different distance in the center than in the corners.

I also have a Canon 70-200 zoom that cost about the same and it is very hard to tell the difference except that the zoom lets me be almost twice as far away from the coin when I shoot.
