Slowbro

At £0.36, this Slowbro is worth a fraction of the Pokéball printing, which sits at £50.21 — a gap of about 140 times the price. The difference tells you most of the value in this card line comes down to that specific variant, so unless you're building a set or after this particular print, the premium versions are where collectors are putting their money.

• NotableThe pokeball printing is 140× this one (£50.21 vs £0.36).
