Congratulations on your fine collection. If I were you, I would definitely not follow the advice to immediately grade your cards with SGC! If you are looking to sell one or more cards in your collection right now and wish to maximize the dollar value, you may find that grading your cards with PSA (given an equal grade to SGC) will yield a far higher return. If I owned your cards and were looking to sell one or more cards, I would consign the card(s) to one of the top card auction houses (REA as an example) and let them have the card(s) graded by the grader of their choice. They may choose SGC or they may choose PSA - they will have an educated and experienced opinion on the best grading company to use to maximize the sale price.
