No simple answer for this question, some fakes are very poor and others are excellent and if you have doubt about a coin show it to a dealer or collector for an opinion.
A genuine 1795 dollar is silver, but it's not pure silver. The coin is a fake if it's not silver.
At the risk of sounding a bit snarky, the best way to tell if it's fake is to hold it in your hand. If it looks like an 1804 silver dollar, it's fake. The 1804 dollar is one of the most famous rarities in all of American coinage. All known specimens have been accounted for and are in museums or private collections. There are oceans of counterfeit ones on the market.
If it's a fake, it's worth little to nothing.
Without examining the coin it is impossible to tell if it is genuine or not. But there are legitimate 1921-S (Morgan) dollar coins struck. If you have a Morgan dollar that has the same weight, dimensions and design as known legitimate coins (and the coin doesn't say COPY or REPLICA or anything like that on it), it is most likely genuine. 1921 is an incredibly common date for Morgan Dollars and most counterfeiters won't bother making deceptive counterfeits of it.
Roughly the value of most fakes, essentially nothing.
Nothing, because it's a fake.
its fake o silver dollars were made in 1799
If it has a motto on the back (the banner saying in god we trust) then its a fake. If its magnetic its fake. If it has a ridge running all the way around the center of the reeded edge the coin it is fake. If the denticles are not all symetrical its fake. Lastly, a real 1843 silver dollar weighs 26.73 grams and has a diameter of 38.1 mm. Anything other than that is a fake.
Not many fake coins are made from real silver or gold. Take it to a jeweler to be tested, most will do this for you.
Yes, I have some counterfeit coins, they are used for reference and teaching tool's.
Please check your coin again. Morgan Silver dollars were minted from 1878 to 1904 and in 1921. No Peace dollars were minted in 1932 due to the Great Depression. If you have a U.S. $1 coin with that date it's a fake. If you have another denomination coin such as a half-dollar, please post a new question with more details.
A 1 dollar denomination silver certificate was not made in 1933 only 10 dollar. That being said if you have one it is fake.....its worth $0.00
