Overview

A silver-colored aluminum souvenir medal commemorating the 1934 Union Pacific streamlined train.

Historical significance

This token was issued for the 1934-1935 Chicago Century of Progress World's Fair. It commemorates the Union Pacific M-10000, the first internal combustion-powered streamlined train in the U.S., highlighting the innovative use of aluminum in its construction.

Obverse (front)

Features a profile view of the M-10000 streamlined train moving to the right. Legends: 'UNION' above, 'PACIFIC' below, '1934' to the left, and 'LUCKY PIECE' above the bottom rocker.

Reverse (back)

Text: 'A SAMPLE OF THE ALUMINUM IN THE NEW UNION PACIFIC TRAIN BUILT BY PULLMAN CAR & MFG. CORP.' Features the ALCOA shield logo and 'ALUMINUM CO. OF AMERICA' below. 'GREENDUCK CHI.' in small letters at base.

Estimated value

$10-$25 in average circulated condition; $40-$75 for high-grade or uncirculated examples.

What drives this coin's value

Condition is the primary factor, as aluminum scratches easily. Presence of original luster increases value significantly.

Grade assessment

About Uncirculated; shows light surface scratches and minor oxidation consistent with age, but maintains crisp details.

Mintage & rarity

Common; produced in high volumes for the World's Fair, but well-preserved examples are sought after.

Authenticity & counterfeit red flags

Authentic pieces are struck, not cast, and should have crisp lettering. Verify the Greenduck Co. signature at the bottom of the reverse.

Notable varieties & errors

Minor variations in the ALCOA logo size and placement exist; some were issued with holes for keychains.

Similar coins

Often confused with the 1933 or 1936 versions of similar Union Pacific 'Lucky Pieces' commemorating later train models (like the City of Salina or City of Denver).

Care & preservation

Aluminum is a soft metal prone to scratching and corrosion from skin oils. Handle by the edges or with gloves and store in a PVC-free coin flip or capsule.
