Certification & Collection

Graded items for top-quality collections!

In the world of numismatics, there are independent bodies responsible for evaluating coins, ancient coins, and other banknotes.

NumisCorner employs the services of the most recognized among them: NGC, PMG, PCGS and GENI. This ensures that the item that you are posed to add to your collection is certified, protected, and authenticated.

The certification process

Each item is evaluated and examined in minute detail by experts, who note any faults, study the wear (traces, scratches, etc.), what is known as the mint luster, that is to say the matt, silky aspect of the surface which indicates a good state of conservation, the quality of the striking, its sharpness, and its patina...

The process for banknotes is similar. The experts note the wear (creases, stains, writing, ...), the crispness and the aspect (for example, the vibrancy of the colors), the proper centering of the printing, and the serial numbers.

Why to acquire a graded collectible item

The process offers a number of advantages. First and foremost, it guarantees the authenticity of your collectible item, which is essential, but it also establishes a quality assessment on the basis of grades shared by numismatists.

Finally, it ensures the value of the item and that of your investment by enclosing it in a case that will effectively protect it from handling and future wear.

How to acquire a graded collectible item

Even though our experts have already guaranteed the authenticity of the items on offer at NumisCorner, and they have been appraised with great care, you still have two options if you wish to acquire a doubly authenticated collectible item:

  1. When you add an item to your cart
    We offer you the option of having your purchase graded by one of the independent bodies mentioned above.

  2. The item has already been graded
    You will receive it in a case directly.
