Please rephrase question.
If it does not have a mint mark above the date, it's worth about $1100. If there is an "S", it's worth about $4000. If there is a "D" it should be authenticated to make sure it's not a counterfeit, as this date/mint mark combination is considered to be extremely rare.
One way to work this out would be to find out the price in 1950 of gold/silver, work out how much Gold £40,000 would have bought back then and then apply today's gold prices to arrive at the answer. In 1950 the average price of a troy ounce was $34.72. The GBP/USD exchange rate was roughly .42p to $1 so £40,000 was equivalent to $95,238. This would have bought ~2743 troy ounces. At today's gold price ($1245) this would be equivalent to $3,415,072 or £2,276,714. Obviously these are not exact but should be more or less correct.
