premium stock is a series 1 parallel ONLY ( grey border on front )
- hobby reserve is a series II parallel ONLY ( has the HR before the card number on back / hobby reserve foil on the front )
- score did pack what they called " premium stock " in series II however the cards are white bordered not grey and instead of the premium stock foil on the front they have the same hobby reserve foil. The way to tell these cards apart from the hobby reserve is they DONT have the HR before the card number on back.
