When the woman is buying two bottles of milk, the grocer asks for 63 cents, saying the price went up. However, the price increase was 3 cents per bottle. It's likely the price should have been 66 cents total, meaning the previous price of a single bottle was 30 cents. It's doubtful the previous cost would have been 28 and a half cents per bottle. (The U.S. last minted a half cent in 1857.) Also, that 63 cents would equate to over $14 in 2024.
The police chief of the city where the crooks set up their racket says he thought such crimes were usually only found in big cities and not a small one like his. However, outside the window of the crooks' office can be seen New York skyscrapers.
