He hasn't been a circulating coin. Chances are it is real since they aren't very rare.
The first real person on a dollar coin was President Eisenhower in 1971. No silver dollar coins have portraits of real people.
A replica of the coin (fake coin) has a value of about US$30, is usually made of non-silver alloy, and has no silver color. As a coin collector, you may still collect a replica coin, because it does have a historical value. A real Sungarei, Chinese Qing dynasty silver coin was minted in 1897 although the minting year was not on the coin. The edge of the real silver coin had the artist's English name, L. GIORGI. Entire coin was in shining silver color, and 1.75 inches in diameter. The current value of a real Sungarei silver coin, 1 Teal, is at least US$10,000.
If you can bend them with your teeth, it is a fake coin.
Trade dollars were US coins made in silver to trade in the far East. However, your coin, if it is an 1884 Trade Dollar, it is counterfeit. There were only 10 examples minted that year, all of them are known. So, when it comes to value, the only value your coin can have is if it is minted in real silver, if it is minted in real silver, it is worth however much silver is in your coin. If it is silver plated lead, or silver plated copper, or non-silver alloy like "nickel silver" your coin is essentially worthless.

Once you found the real director of the radio tower he will give it to you.
It looks like the back of the coin, with a real big eagle.
There is a real Bill of Rights coin but it is a commemorative coin minted in 1993. Since yours has a 1991 date and "one troy ounce .999 fine silver" on it, I think you probably have a bullion coin and it is worth whatever the silver in it is worth on any given day.
No U.S. silver dollars have an Indian Head design, so if you have one it's not real. A genuine silver dollar coin dated 1851 would be a Seated Liberty coin. I have seen many 'fantasy' silver rounds with the Indian Head design with different dates, but they all have the 1oz .999 fine silver markings somewhere on the coin.
The value of a 1991 Garfield coin that is 1 ounce of fine silver will depend on the current market price of silver. You can check the current price of silver online or at a local coin dealer to determine the approximate value of the coin.
