Over his legendary 15-year career at Anfield, Bill Shankly spent a total of £1.33 million on transfer fees to build his era-defining squads.
This modest sum (by today's standards) laid the foundation for the club's dominance. To answer your specific request, here is that amount converted into the currency of his early days:
The Conversion
In the pre-decimal currency system used for most of Shankly's tenure, £1 was equal to 20 shillings.
£1,330,000 X 20 = 26,600,000 shillings
Bill Shankly spent 26,600,000 shillings to transform Liverpool from a Second Division side into the "invincible" force he dreamed of.
Why this matters
Shankly often spoke about the value of money in relation to the working man's struggle. One of his most famous quotes about pressure actually referenced this unit of currency:
"Pressure is working down the pit. Pressure is having no work at all. Pressure is trying to escape relegation on 50 shillings a week. Pressure is not the European Cup or the Championship or the Cup Final. That’s the reward."
For the price of about 532,000 "weeks of pressure" (at 50 shillings a week), Shankly bought legends like Ian St John, Ron Yeats, Emlyn Hughes, and Kevin Keegan, effectively changing the history of the club forever.
