First of all, silver U.S. quarters dated 1964 and earlier are 90% silver, not pure. As far as 1964, it's an extremely common date, currently worth about $4 for the silver content.
No, dimes dated 1965 and later are not silver and unless in mint packaging are only worth 10 cents.
First thing is, if the quarters are all dated 1964 or before they are 90% silver. The average buying price of 90% silver coins is 17 times face value as of 2-14-11. So 500 X 17 = $8,500.00. Some buyers pay more, and some less, it depends on the spot price of silver at the time of sale.
Not a meaningful question. It depends on their dates and mint marks. As a general rule, halves dated 1951-64 are worth about $7 for their silver content. Halves dated 1965 to 69 are worth about $3. Anything from 1971 to today is a common circulation coin worth 50 cents. If your halves are older than that you'll need to check them against a price guide such as the one at Numismedia.com
If they are dated 1964 or before, they are worth at the very least around $2.15 each, if they are dated 1965 or later, they are simply worth 10 cents.
Dimes dated 1964 are made of 90% silver and are worth about $1.35. Dimes dated 1965 are made of copper-nickel and are worth 10 cents.
If you have a U.S. silver dollar dated 1790, then you have a counterfeit. The mint did not start making silver dollars until 1794
This is not done at the mint, rather, a third-party has punched two dates in it and gold plated it. It is only worth what a circulated Kennedy half dollar (because it has been damaged) of that date is worth, there is no extra value. If its dated 1964 it is 90% silver and worth about $8 in scrap silver. If it is dated 1965-1970 it is 40% silver and its worth about $3.25 in scrap silver. If it is dated 1971-present it is just worth 50 cents, nothing more.
Depends on the year, ones dated 1971 and later are only worth 50 cents. Ones dated 1965-1970 are 40% silver and worth about $4.50 in melt value. Ones dated 1964 and before are worth about $11.50 for their silver content, though some years/mintmarks make them worth more than their silver value.
how much is a peterborough silver dollar worth with sir sandford Fleming dated 1827-1915
No US quarters dated 1966 are silver. The only US quarters struck in silver are dated 1964 or before with the exception of silver proof sets (most proof sets are -not- silver and silver proof sets are marked as silver) but those are dated from 1992-present.
Sorry no US silver dollar coins dated 1826
If it's dated 1985, that would be zinc, not silver. It's worth one cent. No US pennies contain silver.
It's a common date, currently worth about $5.
U.S. silver dollars dated 1935 or earlier are worth at least $16 based on the current market price of silver (18 November 2013).
This coin is 40% silver. Too bad it is not from 64 or earlier, as those were 90% silver. It is worth a dollar or two.
Half dollars dated 1964 and earlier are 90% silver and are worth about $11 in silver content. Keep in mind that proof, error, and key date coins may be worth much more than pure silver content. And from 1965-1970 the half dollar was 40% silver and is worth about $4.50 in silver content. Half dollars dated 1971 and later are not silver unless found in a US mint silver proof set. Note that any half dollar made during 1965-69 is only partially silver and is worth about $3. Halves dated 1971 and later contain NO silver and are only worth 50 cents.
