In the scene where Rose hands Jack the dime for drawing the picture of her, it appears to be a FDR dime. Correct me if I'm wrong, but this movie is set in the year 1912, FDR wasn't elected until 1932, and the dime wasn't minted until 1946.
But, if they had used a 1912 dime, would today's audience have recognized it as a dime? I'd bet they used a newer one so we'd know what was going on. Good eye, anyway!
Although her fingers partially obscure it, the coin that Rose gives to Jack is generally agreed to be a Barber dime, minted 1892-1916. The Barber dime is distinctive because the portrait of Liberty on the head of the coin faces the right, not the left.
Incorrectly regarded as goofs: Although her fingers partially obscure it, the coin that Rose gives to Jack is generally agreed to be a Barber dime, minted 1892-1916, not a modern dime as some viewers have incorrectly asserted. The Barber dime is distinctive because the portrait of Liberty on the head of the coin faces the right, not the left.
