You need to be more specific, The US has made MANY silver coins of different denominations from 1794 to 2011.
With no rare dates they likely are only valued for the silver.
These coins are NOT rare and are worth face.
That depends on which rare coin you have. Some rare coins are worth only 150 dollars in average circulated condition while others are worth thousands of dollars. To get a more specific answer include the date and denomination of your coin.
this rare u.s. coin is worth however much a man will pay for it
Assuming it is a coin from circulation and not a rare date it is worth the bullion value of the silver in it, about $22 at today's exchange rate. Certain rare dates, mint marks and coins with exceptional degrees of preservation will be worth much more than that but without more information it's impossible to be more specific.
It would be worth about $21,500 or so. Of course, that is just the silver melt value and it depends on silver spot. Similarly, rare coins in there might sell for more than just bullion value. Of course, rare coins are rare to find in bags sold by face value, but it is always possible that something may have slipped past the coin dealer's eye.
Do You Have Any Silver? Those are the words I use with my bullion dealer if I'm looking for silver coins. Silver coins do not circulate and they are incredibly rare to ever find in change in the US and Canada because they are worth multiples of face value.
It is not rare, just expensive. But, you can get small silver coins for as little as $2.
No simple answer, many US silver dollars are considered rare for different reasons, be more specific and post new question.
The value of silver coins depends on the year, the mintmark and the condition along with the denomination and country of origin. All silver coins (99.9% of the time) have a premium over face value because of the metal they are struck in. However, rare coins are worth more than melt value and larger coins are worth more than smaller coins. Without knowing your coin's denomination, country of origin, year, mintmark and an estimate of condition, it is impossible to assign a value to it.
It depends on the coin. Some are only worth their bullion value, if it's a common date in circulated condition (such as a 1964 Washington quarter). If it's a rare date, or it's in mint condition, then it's more valuable to collectors.
It depends on the year and condition. Common or well worn coins are only worth their silver content, which would be around $26 at current market prices. Coins in better condition are worth more, as are those with a more rare date or mint mark.
