A true macro lens will have a much shorter min focusing distance. Also, your lens is listed as having a magnification of 1:5.3. A true macro lens will have a magnification of 1:1. A magnification of 1:1 equals life size. This means that the mint in your case, would be the same size on the sensor of your 30D as it would be in real life. What you are getting with your current lens is only 1/5 of life size.
FWIW, a true macro lens also has a flat field that "normal" lenses do not. This can be extremely important for some macro subjects. Extension tubes can't change a curved view to flat field.
