It's worth exactly one pound.
A Sovereign is Sterling coin. In 1880 a Sovereign was worth a Sovereign or One Pound. It's face value has not changed since it was reintroduced into the currency in 1817.
August 17, 2009 One half pound of silver is worth $102.50 today. The date of mintage and the name of the private mint does not increase the value.
If the coin is that worn that the date is illegible, it will be worth nothing.
The date and mint mark are on the the edge of the coin
You need to know the date but probable a pound.

What is a silver dollar from 1702 worth today
Then that coin is a error and is worth a whole lot more than a dollar First look at the edge of the coin for the date & mintmark.
The coin is worth one dollar. Without a DATE in your question that's the best answer. Post new question.
To date, no horse has ever appeared on a British One Pound coin. There has been a unicorn as part of the Royal Arms on the 1983, 1993, 1998 and 2003 One Pound coins.
It depends on why it doesn't have a date. If the coin is worn, the date was eroded due to acid, etc. it is worth simply 1 cent. If the coin is not worn at all and in perfect condition and there is no date or cracks where the date would be, it could be die deterioration and might be worth a dollar or two to an error collector.
If I understand the question, you have a Sacagawea dollar coin with no date on the obverse (front) of the coin and you think it should have a 2000 date on it? The coin was made after 2008. From 2009 to date, the year the coin was struck in is on the edge of the coin.
