Yawn.
But actually GBP 127 = 337 USD (in 1972)
If you invested $337 in the S&P 500 at the beginning of 1972, you would have about $49,235.87 at the beginning of 2021, assuming you reinvested all dividends. This is a return on investment of 14,510.05%, or 10.71% per year.
This investment result beats inflation during this period for an inflation-adjusted return of about 2,168.62% cumulatively, or 6.58% per year.
If you saved that 127GBP back then, you could afford 2 Solstice decks today.
And today's Majik seems rather good value then.
