Solosis

Raw copies of Solosis are shifting steadily—about 4 a week over the past fortnight—with a median sell price of £23.13 across 26 UK sales in the last 90 days, so the £23.99 price tag is spot on market. The cheapest ask sits at £19.85, which is 34% under the median ask of £29.96, giving you room to negotiate if you're buying. Grading isn't the move here: PSA 10s haven't sold in two weeks despite climbing 32% to a £403.11 median, and you'd need a flawless copy to justify the 10.6× jump in value over a PSA 9.
