Welcome back!
A couple of things about your coin...
The various spots that appear on the obverse of the coin may be due to an improper dipping of the coin in its past. Often, a coin that is dipped but not properly rinsed and dried afterward can develop the sort of whitish spots seen in the image of your coin. Such spots have the potential to slowly damage the coin's surfaces.
I also see some greenish spots on the coin's reverse which could be related to PVC contamination. It's always difficult to tell from images, so I'd have a knowledgeable coin person have a close look at the coin to be sure and to guide you on what to do next concerning eachy of the potential issues I've mentioned.
In terms of the die crack on the coin's reverse...die cracks are known for the Stone Mountain half-dollars, though not necessarily common.
In terms of the die crack impacting the coin's value, I believe that it would have minimal impact. If you were to find a collector who is interested in such things and specifically collects them, you might be able to get a small premium. Otherwise, my experience suggests that it will not change the retail value much either up or down. US commemoratives are not generally collected by die state like some other US coin series.
