In the A time travelers dilemma: where to store vintage documents for hundreds of years thread, the question was raised of having to pay e.g. a law firm for document storage and thus eating into potential profits. I was going to point out that inflation over the centuries means that fees were much cheaper back then; but then I realized that that’s only measured in the intangible medium of dollars or British pounds. If you had to come up with the actual specie to pay a fee in pounds Sterling in the Eighteenth century, maybe the inflation since then has been less dramatic? In other words, what does the inflation index look like when keyed to the price and buying power of silver or gold?
