10 Dollars Tutankhamun, Death Mask

Sierra Leone has issued commemorative silver dollars under this nominal denomination for decades, contracting with private minting houses — primarily in Europe — to produce collector pieces that bear no meaningful relationship to the country's actual currency, the leone. The "10 Dollars" face value is a legal fiction maintained to give the piece status as official coinage.

The encapsulated sand here is sourced from Egypt — almost certainly marketed as originating near the Valley of the Kings, where Tutankhamun's tomb was discovered by Howard Carter in November 1922, exactly a century before this coin's issue date. That centenary is the entire reason this piece exists.
