Assortment of U.S. Silver Dollars and a 'Tails You Lose' Challenge Coin

This collection features several U.S. silver dollar coins and a novelty challenge coin. Prominently displayed are three distinct U.S. silver dollars outside of protective sleeves: a Morgan Silver Dollar, dated 1888, showcasing the left-facing profile of Lady Liberty with 'E PLURIBUS UNUM' above her head and the date below; a Peace Silver Dollar, dated 1922, depicting Lady Liberty's head facing left with a radiant crown and 'IN GOD WE TRVST' visible just below her neck; and a third silver dollar, possibly a Walking Liberty Half Dollar, though only the obverse showing Lady Liberty walking is partially visible. The visible silver dollars appear to be composed of 90% silver, a common composition for these U.S. coins from their respective eras. Their condition varies, with the 1888 Morgan Dollar exhibiting some wear consistent with circulation, including softened details on Liberty's hair and facial features, and a noticeable patina or toning, which is typical for aged silver. The 1922 Peace Dollar also shows some surface wear. Two additional silver dollar coins are partially visible in what appear to be plastic coin holders, one of which is clearly a Morgan Dollar. The inclusion of plastic holders suggests an attempt at preservation. Alongside these historical coins is a modern challenge coin with a prominent skull motif. This coin features a black outer rim with 'TAILS' and 'YOU LOSE!' inscribed in white lettering. The central field is a vibrant red enamel, within which a stylized silver-toned skull is depicted. The skull has three red 'blood drops' around its left eye socket and additional red splatters over the forehead, creating a somewhat macabre and edgy design. The craftsmanship of the challenge coin involves enamel work and raised metal details, indicative of a modern manufacturing technique for novelty or commemorative items. The overall presentation suggests a numismatic interest, possibly for display or collection, blurring the line between historical currency and contemporary memorabilia.
