Your currency will come in a fantastic hard plastic grading slab that will keep the bill safe and sound. Many currency grading companies use flimsy sleeve-type holders that can still allow damage to your currency. SGS offers what is probably the best holder in the business; a sturdy hard plastic slab that is 1/4 inch thick. It is thick enough to protect your currency and small enough in overall size to store easily. And of course your slab will come sealed in the famous SGS gold seals, and will come with a Certificate of Authenticity (COA) with the Serial Number for your slab.
