Old Money will tell you how much a specified historical amount is equivalent to at any other point (1264 – 2008). It presents two figures; one based on the Retail Price Index and another based on average earnings.

The data is derived from the data available on MeasuringWorth. The full data set isn’t used – I took 5 year averages to reduce the size, so I recommend you visit the original source if you want more accurate figures.
