U.S. dimes dated 1964 and earlier contain 90% silver with 10% copper. Dimes dated 1965 and after contain absolutely no silver.
U.S. dimes, quarters, half dollars, and dollars dated before 1965 contain 90% silver with 10% copper.
Up to and including 1964 they were 90% silver. After 1965 they contained no silver except for special coins the mint produced for collectors.
Coins in the United States were originally based on their metal value. Thus, a dime weighed 10/25 as much as a quarter and 10/50 as much as a half dollar. Basically, a dime was so small because it was supposed to contain about 1/10 as much silver as a silver dollar did. Although the composition of these formerly 90% silver coins is now cupro-nickel, the relative weights still survive; if you have a pile of dimes, quarters and half-dollars (and old Eisenhower dollars as well, but not any of the "golden" dollars), you can ascertain the face value based on weight alone (22.68 grams to the dollar (or, put another way, a pound of such coins is worth $20.00).

Much of the reason for events and doctrine taught in the New Testament are to be found in the Old Testament. The New Testament would be incomprehensible without the Old. The reason for Christ's coming to earth and why humankind are in need of salvation can be found in the Old Testament, particularly in Genesis.
It depends on the current price of silver. Old silver dimes contain about 1/14 of a troy ounce of silver, so if for example silver is $42/oz, a silver dime is worth about $3 so it would take 30 new dimes to buy an old one.
50 old silver dimes weigh around 175 grams in total. Each old silver dime weighs approximately 3.5 grams.
U.S. dimes, quarters, half dollars, and dollars dated before 1965 contain 90% silver with 10% copper.
It really depends on the date of the coin, post new question with a date.
No. All dimes minted since 1946 use the same design; the only difference is the mint mark. But from 1965 to 1967 the use of mint marks was temporarily discontinued while the Mints worked to strike new clad coins to replace the old silver ones, so 1966 dimes don't even have mint marks.
Other than size, appearance, and monetary value... not much. If both were minted pre 1965, then they are both 90% silver. Both underwent a few different styles. For the silver dollar, there were Liberty, Morgan, and Peace designs. Dimes were Liberty, Barber, Mercury and Roosevelt.
No 1911 silver dollars were made, look at the coin again and post new question.
Occasionally old silver U.S. dimes, quarters, and half dollars show up, but most have been pulled from circulation by collectors. Silver coins are seen less frequently in other countries that have redesigned coins since removing silver.
If it's a U.S. coin the denomination and date are the best way to determine. Dimes, quarters, halves, and dollars minted before 1965 are 90% silver. Among old denominations, half-dimes and some 3¢ coins are 90% silver as well. Half-dollars from 1965 to 1969 are 40% silver. Dimes, quarters, and dollars minted in 1965 and later have no silver in them. They're either cupronickel or (for dollars from 2000 onward) brass. Cents have never been made of silver. 1943 cents are steel. Nickels made during WW2 are 35% silver. Foreign coins may be much more difficult to deal with, but again the date and denomination are the places to start.

New friends are silver, old ones gold.
If it's 1965 or later, it's worth 10 cents. If it was made before 1965, it's worth at least $1.50. The reason for the big price difference is that 1964 was the last year dimes were made of silver, and so they've mostly been melted down for their silver content, making dimes that old rare.
