Let's break them down: Pros of Grading with PSA: Robust website: PSA has a well-built website with easy-to-use online tools such as their submission page and account interface Tools for Collectors: PSA maintains an online Price Guide to assist you in finding the market price for PSA-certified collectibles, an online Pop Report that allows you to search the population of any graded PSA card and verify the certification details of a card by the Certification number listed on the graded card, and the Collectors Vault which allows users to use a single platform to authenticate, grade, research, vault, buy, and sell Partnerships: PSA has a partnership with Goldin marketplace that will soon allow customers with access to the Collectors Vault to list items for sale on Goldin and to 'vault' items purchased through Goldin Market: Gem-Mint PSA cards tend to maintain a higher market price that other Gem-Mint grades from other companies (note that this can fluctuate and change over time) Cons of Grading with PSA: Limited Grading Scale: there is no half-point grade available between 9 and 10 on their grading scale (no 9.5) Turnaround Times: current turnaround times for bulk and economy grading are extremely long and not guaranteed High End Cards: the Premium grading prices for high end cards are very high CGC Pokemon Grading Review CGC (Certified Guaranty Company) began by grading comic books in 2000 and was widely embraced by collectors
