For this initial review of the major vaulting services we’re focusing on the core use case of storing, buying, and selling graded cards on each vault’s marketplace. We use two categories: Vaulting and Selling to rate each service. Each category have a number of criteria rated 1 (poor) to 5 (excellent). The scores are averaged to provide an overall rating.

We also added up all fees to vault, sell, and receive cash back in your bank account - for a single card - to create and apples-to-apples comparison of selling costs.
