Hammered Copper Worry Stone

If you're unfamiliar, Shire Posts uses centuries-old metalworking techniques to create hand-pressed collectible coins one at a time. They have as many purposes as you can think of — from an everyday good-luck charm to a literal token of your appreciation for someone special. This particular one is made of solid copper, with a satisfying weight and hammered finish that'll form a beautiful patina over time.

In 2001, founder Tom Mallinger bought an antique coin press and began making collectible, good-luck coins by hand-engraving steel dies and pressing them one at a time. The coins he made as a weekend hobby caught the attention of author George R.R. Martin for the Game of Thrones series — which helped propel the operation into a full-fledged, successful family business.
