Ive noticed a lot of toned coins in NGC holders. I believe they tend to grade higher vs PCGS when it comes to toned coins. I've also noticed a lot of toned coins in NGC holders with the * designation. I believe what people were wanting clarification on is if you were talking toned or colored as in enameled or painted coins. As to your question as to how are NGC and ANACS still in business. I believe ANACS pulls the market share of people who want their coins graded and don't want to have to pay a membership fee. They are also top notch when it comes to varieties. NGC is just about up there with PCGS. Most of the time PCGS coins will command a higher premium but not always. Also with PCGS and NGC offering registry sets on their websites, which have become very popular lately, they have added a ton of competitive collectors to their ranks.
