Re: One problem with this
According to the Measuring Worth website, a 6d Mars bar in 1955 going by retail price index would be worth about 60p today. Coincidentally the current price of a 51g Mars bar from Tesco.
Using other measures of 'value' 6d in 1950s is worth up to £2.50 in terms of earnings or share of economy.ie it took more to earn that Mars bar in the 50s.
