This question comes up fairly often and is a common misunderstanding. US $1 coins made up till 1935 aren't called "eagles" and they don't contain 1 oz of silver. They were ordinary circulation coins made for use in daily commerce. While they do contain silver, it's not as much - about 3/4 of a troy ounce.
"Silver eagles" are modern (1986 and later) coins sold by the Mint as investment pieces, not for spending; their value is linked to the current price of silver and the "$1" value is purely artificial.
The coin you have is often called a Peace dollar because it was minted to celebrate the end of WWI. Its value when minted was in fact exactly $1 because silver was much cheaper and its price was controlled. Today it has value not only for its silver content but for its interest to collectors. There's more information at the Related 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.

To estimate the value of £8,000 from 1927 in today's currency, we can use historical inflation data. In the UK, the average inflation rate since 1927 is around 3-4% per year. Based on these estimates, £8,000 in 1927 would be equivalent to approximately £400,000 to £500,000 today. However, for a precise conversion, consulting an official inflation calculator or specific historical inflation statistics would be recommended.

All Peace dollars have this. It's just a normal part of the design and adds nothing to the value.
