Internet Coin Buying Tips | Part 5

Purchasing Slabbed/Graded Coins.

This can be tricky. There are a number of things to consider before bidding on a TPG (Third Party Graded) coin. We have found the most reliable grading companies to be PCGS, NGC, ICG, and ANACS. Their grades seem to be the most consistent and reliable, but mistakes are still possible. Remember that grading is subjective and, as such, is not an exact science. The best way to approach it is, "Buy the coin, not the slab." By this, I mean to look closely at the coin's detail. I have personally seen many slabbed coins that I have disagreed with the assigned grade. Learn to grade for yourself so that you know what you are looking for. The books mentioned above will help you to learn. Also, the ANA has a coin-grading course that is invaluable in learning the grading points and being comfortable with your own assessments.
