Jim I have both the Nikon AF-S NIKKOR 24-85mm f/3.5-4.5G ED VR Lens and the AF micro 60mm f/2.8D lens...
As wingclui44 mentions they are two very different optics... with very different applications...
The short answer to which is "worth more?" the Nikon AF Micro-NIKKOR 60mm f/2.8D Lens current is listed at $516.95 while the AF-S NIKKOR 24-85mm f/3.5-4.5G ED VR is listed at $496.95 so the 60mm is worth more new...
But that is not likely what you want to hear, instead like so many other hobbyist you are actually seeking validation for your next investment...
To cut to the chase, since you actually don't know enough to make a rational decision here I would strongly suggest you stick with your 24-85mm in as it is far more forgiving for hobbyist...
The Nikon AF Micro-NIKKOR 60mm f/2.8D Lens is a professional lens and as such likely only has worth/value to a commercial shooter... Not a hobbyist who may be challenged to deploy it effectively...
FYI: I use my Nikon AF Micro-NIKKOR 60mm f/2.8D Lens infinitely more than the inferior 24-85mm hobbyist lens which shipped as a standard lens with the D600/D610 and although it is vastly better than the popular 24-120mm which is no match for the good performance you will continue to enjoy with your AF-S NIKKOR 24-85mm f/3.5-4.5G ED VR.
But please don't take my word (or any other UHH member's word on this) instead look to a magazine editor vastly more experience than you will find on UHH

There will be no need to query others at that juncture...
I wish you well on your photographic journey Jim
