Coalossal

This Coalossal has been stuck at £0.91 for 25 days while the set has dropped 14.5% over the last month, so there's little momentum here. The foil version trades at £3.82—4.2 times the price—but the real outlier is the plain printing of the same card, which sits at £6.93, making this holo worth 7.6× less. Before listing, check which version you've actually got, because the pricing gap suggests condition or grading could be doing heavy lifting elsewhere.
