I’ve never considered grading as the sentimental value is higher than what the grading value would give. And I’d never sell it so there is no point. It would grade very well though as all corners are perfect, there’s no chipping and centering is good.
One thing about these old boxes is that all the cards stick together so surfaces of 99% of the cards have varying degrees of damage. Luckily the scoring king hits are on bottom of the packs face out.
It’s one of the most beautiful looking cards in hand, especially when held up to light. Amazing for the printing technology back in the day.
