Modern dimes are not "silver-coated". They are made of a copper core with outer cladding of cupronickel. No silver at all. Another Answer: Prior to 1965 dimes were 90% silver.
US quarters (and dimes, half dollars and silver dollars) were never made of pure silver. Through 1964, they were 90% silver and 10% copper. From 1965 onward, circulating quarters have been produced from 91.667% copper and 8.333% nickel (although some proof coins have been produced of 90% silver in recent years for collectors). Dimes and quarters were changed to copper-nickel in 1965 when the price of silver increased to the point where coins were worth more than their face value. It was possible to go to the bank and get a roll of quarters for $10, then turn around and sell it to a metal dealer for 3 or 4 times that amount. As a result, most silver coins disappeared from circulation. Half dollars were changed to 40% silver in 1965, then to copper-nickel in 1971.
From what country? Please post a new question. The U.S. stopped making silver dollars in 1935.
AnswerIn 1965, the US Mint began producing Roosevelt dimes and Washington quarters using the current copper-nickel clad "sandwich" metal, because the price of silver was going up and it became more profitable to melt the coins than to spend them. For example the metal in a silver quarter became worth much more than 25 cents so people would go to a bank, get rolls of quarters, and immediately re-sell them to a metal buyer at a large profit. Nearly all silver coins disappeared from circulation because of hoarding and melting. For a while half-dollars were made out of a copper/silver clad composition that was "debased" to 40% silver, but by 1971 even the half was converted to copper-nickel.Since around 1986, though, Proof silver quarters, half-dollars, and dimes have been offered to collectors through the US Mint.
When does the old fifty pound note go out of circulation
Many British coins were once made of silver. Threepence, Groat, Sixpence, Shilling, Florin, Halfcrown, Double Florin, Crown, Maundy Coins amongst others. If you go back in time far enough, even pennies were silver. From 1947 onwards, no British general circulation coin contains any silver.

In Great Britain, the last Threepence coin produced for circulation was minted in 1967. A proof-only Threepence coin was also produced in 1970. Finally, small numbers (usually about 2,000 to 4,000 each year) of silver Threepence coins are produced annually (as they have been for several hundred years) as part of four-coin Maundy sets. The Threepence was initially to be withdrawn and demonetised on the introduction of decimal currency in 1971, but they remained legal tender until about 1974 or 75.

After the pulmonary circulation is complete, the blood goes back to the heart.

All current circulation bills are Federal Reserve Notes so depending on the dates you're interested in you can simply look in your wallet. Older dates of Federal Reserve Notes (before 1999 depending on denomination) and all silver certificates are pretty much out of circulation though, so you'd need to look on eBay, go to a coin and currency show, or visit a dealer.
They destroy it. Go figure!

Yes indeed they do. Sears sell the bits and the drills that the bits go into. They sell these together or separately at a reasonable price and at any quantity.
