Hello Shatzi and welcome. If you do a search for coin grading, you will find a number of threads on this subject.
The top 4 most respected companies are PCGS, NGC, ANACS, and ICG. Different people have different preferences out of these 4. Personally, I prefer ANACS as they seem to have the most consistent and toughest grading standards. PCGS and NGC generally get more money in sales, but I feel that this is because they tend to overgrade. You will get many different opinions here.
