Are screwdown cases better than getting cards graded?

Answer 1

A screw down case is great for protecting a valuable card that you want to display. A card that is graded is encapsulated in a sonically sealed card holder not only for protection but to protect the interity of the card graded. The card holder is tamper proof so that the card graded can not be switched with a card of a lesser grade.

The higher the grade, the more desirable, and consequently, the more valuable the card. Nowadays nearly all valuable sports cards are graded using the 10 Point Grading Scale established by Professional Sports Authenticator (PSA) in 1991.

For this reason it would be better to have the card graded. It would be as protected as having it in a screw down case, and more valuable. Graded cards in general can sell as much as twice the value or more than a non graded card.
