Question of value.....

Questions:
1. What is the best method of placing value on a CD... searching E-bay completed auctions?
2. Is there a general rule for grading CD's?
3. I have a polish: Micro-Smooth, purchased from Mapleshaderecords.com. Are polishes recomended for collectibe CD's?

Thanks in advance.
