10 Dino Dinosaurs World Series - Spinosaurus

The "Dino" series, marketed under a Spanish issuer, occupies an awkward category — neither legal tender nor pure novelty item, but a privately produced polymer collectible designed to mimic banknote format closely enough to appeal to thematic collectors. The Spinosaurus entry is one of at least ten denominations in the run, each assigned a dinosaur genus. Spain has no central-bank authority behind this; the issuer is a commercial operation exploiting the unregulated collectibles market.

Spinosaurus itself is a reasonable choice for the series — its North African origin and mid-Cretaceous dating make it genuinely distinct from the more commonly licensed theropods, though that distinction is unlikely to have driven the selection over simple visual drama.
