My regular go-to for getting a feeling for the value of old GBP and USD prices is measuringworth.com, which gives a range of values based on not just the regular consumer price index-based inflation, but also some additional indices, like the evolution of wages and GDP.

(Edit: Somewhat funnily, it seems one of the help pages on measuringworth.com actually uses the example of the Titanic: https://www.measuringworth.com/tutorial4.php https://www.measuringworth.com/tutorial4.php)
