Larger three are 1.25" and smaller is 1". Three have backpapers while last does not. First is a rarity showing long horn steer and reading "'Steer' For The Iron Mountain Route" with early fair date of 1903. Next is portrait of "Rolla Wells/For World's Fair Mayor." He was the city's mayor during the exposition. Third is another first seen with center text reading "World's Fair Day Oct. 15/B.I.D./Are You 'Wid Us.'" We don't know the meaning of the acronym. Last is another rarity issued by "Nat'l Life Ins. Co." given away by their St. Louis manager and depicting eagle on shield which holds small text "'I'll Make Assurance Double Sure.'" Two essentially microscopic tiny craze lines. All four pieces display NM to Mint.
