The grading math doesn't work here—a PSA 10 sits at £129.99 but hasn't shifted in a fortnight, whilst raw copies like this are £41.77, so you're looking at a 3× multiplier that simply isn't moving. The jump from a PSA 9 (£43.98) to a PSA 10 (£129.99) is steep enough that only a truly flawless copy would justify the grading costs and wait time. That said, this is the fourth most valuable card in the Celebrations Classic Collection of 25 priced cards, so there's genuine demand in the set.
