1846 was the first year for an "O" mintmark on a dollar coin. Look at the coin again and post new question.
It's just a presidential dollar coin value is $1.00
The only US coin that has the dual-dates of 1797-1801 on the obverse is a 2007 John Adams Presidential dollar, the date and mintmark is on the edge of the coin. If you got the coin from a bank or change, it's face value. Only a proof or mint state coin will have a premium.
The US coin looks very much like a modern US penny
Look at the coin again. The first US one cent coin was struck in 1793.

About the width of a US penny (one cent coin)
A genuine 1801 Bust silver dollar is worth no less than $700 and possibly over $10,000 depending on condition. If by chance the coin is golden in color, with a picture of Thomas Jefferson and the dates 1801-1809 on it, then it's a modern presidential dollar, worth one dollar.
The US didn't mint any $1 gold coins in 1801. My guess is that you almost certainly have a modern presidential dollar coin. 1801 is the date of the start or end of that president's term - the minting date is on the coin's edge. And it's made of brass rather than gold so it's only worth $1. Feel free to spend it. Hundreds of millions are being minted.
The current US penny coin features the Union Shield Crest on the back side of the coin. A banner with the words one cent goes over the shield.
That depends on the denomination of coin.
No such US coin exists. You might have one from a different country, but you'd have to specify which country you were talking about.
It may have been plated with gold but it adds nothing to the value of the coin.
