Q.) Does SGC accept cards graded by another company to be crossed over?
A.) We do offer a crossover service that reviews cards graded by other grading companies. The cost is $7.00 for the card to be reviewed, and possibly an additional amount based on the value of the card if the grade is going to meet the requirement you are looking for or if you want a quicker turnaround time on the cards. Make sure to put credit card information on the bottom of the invoice.
