Concept:
• The theme of the story is escapism from the harsh realities, insecurities, and stresses of the modern post-war world.
• Time travel in literature often requires the character to adapt to the material conditions of the destination era, including its monetary system.
Step 1: Identify Charley's intended destination
Charley wanted to escape to Galesburg, Illinois, specifically to the year 1894. He viewed this era as a peaceful, idyllic time far removed from the anxieties of the 20th century.
Step 2: Explain the practical necessity for old currency
When he first visited the "Third Level" at Grand Central Station, the clerk at the ticket counter refused his modern bills, calling them "not money."
To buy two tickets to Galesburg for himself and his wife Louisa, he needed "old-style" bills that were in circulation during the 1890s.
Step 3: Synthesize the final answer
Charley was keen to buy old currency because he intended to travel back to the year 1894. Since modern currency was useless in the past, he exchanged his life savings to obtain old-style bills to pay for train tickets to Galesburg.
