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

Cut edges are a problem in my mind. The CD edges are sealed and cutting them opens the edge of the aluminum layer to possible corrosion.
Green or black edges does nothing to the resale value, as it can be easily remove if desired.
You cannot put the cut off edge back.
My $0.02

Yes, just like circumcision, there is no going back. The good part is that it hurts quite a bit less.

Viridian, thank you for that "tip"

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.

All kidding aside, pretty much any modification of a CD would diminish the saleability of that item in the market place. Does that mean that you can expect to get less money for it? Probably, but not necessarily. It will certainly limit the pool of buyers, as many collectors will not touch an altered item. But it is possible that there are buyers out there that would still pay you $100.00, though I would not give you more than $10.00 for it. And the more rare an item is, the less likelyhood that they will have a choice between an unaltered example and your modified example. In the end, supply and demand are king, but remember, you only need one buyer. Those are the vagaries of a free market.
