This large aluminum token was made for the Union Pacific Railroad in 1934. The front is embossed “Union Pacific-Lucky Piece-1934” and measures 31.75mm. The back is embossed with information about the aluminum used in building the new Pullman cars for the UPRR and also features the ALCOA logo. I believe this piece was made for the The Pullman Co. and UPRR as a give away for the 1935 Worlds Fair that was held in San Diego, CA. The token is in excellent condition with very little wear with a nice patina on the back. Please email any questions. USPS shipping.
