The authenticity and condition of each card is independently assessed by hand by 2 to 3 experts equipped with sophisticated analysis equipment and with continuous information monitoring to keep their knowledge up to date in order to maintain a faithful and harmonised application of our grading scale. However, our graders are computer-assisted for certain tasks requiring mathematical accuracy, such as measuring the centre of gravity. Safeguard's aim is to offer expertise that combines the analytical skills of an experienced human eye with the rigour of an objective assessment.
