2007-2010 $4 Fossilized Dinosaurs 5-Coin Collection

These Royal Canadian Mint prehistoric coins feature a selective aging effect creating a powerful impression of fossilized dinosaur bones in stone. This technique ensures no two coins are exactly alike. Each 99.99% pure silver coin is unique and—with a design that was developed in close collaboration with palaeontologists at Alberta’s Royal Tyrell Museum—and is an original and compelling keepsake of one of humanity’s great fascinations.
