You have what's commonly called a Morgan dollar after its designer George Morgan. Please see the Related Question for more info.
To clear things up:
> It's not just any lady, but Miss Liberty.
> It's "In God WE Trust", not "In God You Trust"
> And all US Coins have the motto E Pluribus Unum on them, so that's not an identifying mark.
No U.S. silver dollars are dated 1830 because none were made. Look at the coin for a .999 fine, one ounce marking. It may be whats called a "Silver Round" that's an ounce of silver made to resemble a coin. The value would be just for the silver.
There is no such thing as an E Pluribus Unum Silver Dollar. That is simply the motto of the US, it does absolutely nothing to identify the coin other than to say it is from the US. But any US silver dollars dated from 1935 and prior are worth at least $33 or so for the silver content, any dollar coins minted after contain no silver and are only worth face value unless in proof condition.
you bend it and compare it to other silver dollar
Unfortunately two different types of silver dollars with the same date were made in 1921 . One is a Morgan dollar and the other a Peace dollar. But you included the motto"E-PLURIBUS-UNUM" in the question posted and this appears on the obverse (front) of the Morgan dollar coins. Circulated coins run from $25.00-$40.00 depending on condition and any mintmark.
Please see the Related Question because the coin isn't a silver eagle. "Silver eagles" are modern bullion coins containing 1 oz of silver and sold by the Mint to collectors and investors. What you have is a $1 coin called a Morgan dollar minted for use in ordinary commerce. At the time the price of silver was controlled and the coin was in fact worth exactly one dollar. Also, All Morgan and Peace dollars carry the motto E Pluribus Unum as do most other U.S. coins so that's not a distinguishing piece of information.

Yes. That's a Morgan silver dollar.
Two different US one dollar coins were made in 1921. One is a PEACE dollar the other is a MORGAN dollar. A Peace dollar is worth more than a Morgan, it has the word PEACE on the rock on the reverse of the coin the eagle is standing on, it's worth at least $70.00 and the Morgan is $33.00-$39.00 but only IF the coins are in collectible condition.
The biggest difference is Peace dollars exist and Liberty dollars don't. A very common mistake non-collectors or amateurs make with US silver dollars is they think because the word LIBERTY is on the obverse of a Peace dollar (or other coins) it's called a liberty dollar. No US coin is referred to as just a "Liberty" coin. Also this comes up with Morgan dollars, but with the national motto E PLURIBUS UNUM because it's on the front of the coin.
A marking of "925" typically indicates sterling silver, which is 92.5% pure silver and 7.5% other metals. Gold jewelry will typically be marked with "9K," "14K," "18K," or "24K" to indicate the purity of the gold.
The marking "925" on a silver chain means that it is made of sterling silver, which is 92.5% silver and 7.5% other metals. "gM8" is not a standard marking for silver and its meaning is unclear. It could be a manufacturer's stamp or a unique identifier.
The "IS" silver marking on flatware stands for "International Silver Company". The flatware is silver plated. Visit the link below for details about other silver markings too.
