As an authorized dealer, we act as a the 'gate-keeper' by first reviewing your submissions and making recommendations as to how each item will grade. While there are no limits as to what can be submitted, not everything is suitable. Grading can be expensive and there are many factors involved in suitablility. Thus, in your financial interests we ask the hard questions: Will the item's value be substantially improved by grading? Will it come back the expected grade? Is grading necessary when all that is needed is authentication?
