Mithril Coat

Worth more than the whole Shire; lighter than linen, harder than steel.

The Mithril Coat is the principal artifact of its kind in J.R.R. Tolkien's Middle-earth, a small shirt of mail wrought from pure silver-steel known as mithril. Described by Gandalf as capable of being beaten like copper and polished like glass, it possesses a beauty that never tarnishes or grows dim. While resembling common silver to the eye, this metal is significantly harder than tempered steel yet light enough to be worn comfortably under other garments. The coat was originally retrieved from the hoard of Smaug by Thorin Oakenshield and later given to Bilbo Baggins. By the end of the Third Age, such items were beyond price, with only a few remaining in use after the Dwarves lost their deep mines.

Lore & Background

In Tolkien's writings, mithril is the only invented metal in his Middle-earth legendarium. Its name derives from Sindarin words meaning 'grey' and 'glitter'. The Dwarves kept their own name for the material secret, mining it exclusively in Khazad-dûm before the Balrog destroyed the kingdom. Before this abandonment, while actively mined, mithril was worth ten times its weight in gold; afterward, it became priceless. Thorin Oakenshield described a coat of dwarf-linked rings as being wrought of 'pure silver to the power and strength of triple steel.' Bilbo later identified a similar small coat made for an elf-prince as 'silver-steel which the elves call mithril.' The Noldor of Eregion also created an alloy called ithildin from it, used to decorate gateways with writing visible only by starlight or moonlight.

Reader's Guide

To utilize this artifact effectively, one must wear it as an under-layer beneath standard clothing and tunic, as demonstrated by Frodo Baggins who kept its presence secret. The armor is described as 'close-woven of many rings' yet supple almost as linen, allowing for unrestricted movement without the burden of heavy plate. Its primary function is defense against physical strikes; it successfully withstood a spear thrust from an orc chieftain and multiple arrow strikes. The coat requires no special training to wear due to its lightness, making it suitable even for Hobbits.
