Would treated CD's or OOP's-hold its value later?

The lathe that cuts the edge of the CD polymer has been about 3-4 years old as a tweak. It is yet to early to decifer if it will start pitting the aluminum or not. A few of my old CD's drom early 80's had the aluminum right to the centre of the Cd and have showed major signs of pitting. hence the concern.
I suppose as Viridian explained- there is no going back! That is fine, but will it drop my re-sale value. Take for example Blues in Orbit- Duke Ellington MFSL's 1st SACD ever, is out of print (OOP) and a 2nd hand copy goes for around $70-$100.
What would the market pay if I did my cuts on it, Nespa'd it and used a CD cleaner(the latter two being not physically noticeable).
What would you pay for it? 50% of the value?
Thanks guys for your feedback.

I have used sound rings on a lot my CD's from Simms to Monster and the manufacture says do not use them on a In dash cd player cause the rings can come off. The rings can be removed and with some elbow grease you can get the adhesive off. It just depends if you hear a difference thats all. I use them on older CD's basicaly 1st generation stuff when alot of the music I listened to in jr high and high school was first being remastered.
I can't hear a difference with the newer ADD or DDD discs though. So someone who was going to purchase something your selling might not want the sound ring on there.

I can assure you that shaving the sides of the cd polymer does not make it sound any better. Nor does coloring the edges with a special marker, but if you want to destroy your CDs because you think it does then knock yourself out.

Viridian/Qdrone/Shawn thanks for your insights. I will stick to no modification, as it's just not seem to be worth the extra 5% sound improvement.
