What you've been told is incomplete and a bit misleading.
First, cents and nickels do not contain any silver. Their composition was NOT changed in 1964. In fact, ALL nickels minted since the 1860s, except for those very exceptional WW2 nickels, are made of the same thing - an alloy of 25% nickel and 75% copper.
Second, 1964 was the last year that higher-denomination coins were made of 90% silver. Starting in 1965, dimes and quarters were converted to the current "sandwich" composition of outer layers of cupronickel bonded to a pure copper core (that's the dark line around the rim of those coins). Halves were made of 40% silver for a few years, and in 1971 that denomination was also converted to cupronickel+copper.
Finally, if anyone tells you that 1943 cents were struck in silver (or lead!) they are again misinformed. For that year only, pennies were made out of zinc and steel so that copper could be used in making ammunition. There is no such thing as a silver Lincoln cent.

A quarter is made of 91.67% copper and 8.33% nickel. However, before 1965 quarters were made of silver.
No, nickel is an element. Silver is another element. Neither are alloys, silver only contains silver, nickel only contains nickel. "German silver", which is not actually silver, does contain nickel. It's a silver-colored alloy of nickel, copper and zinc.
There are several ways to tell the difference between nickel and silver. Silver is much softer than nickel. However, nickel will shine with a cloth while silver needs special cleaners. Finally, silver is more reflective than nickel.
Jewelry cannot be made with 100% jewelry as it is not strong enough. Nickel or copper is added for this purpose. Click on these links to see beautiful silver jewelry made by artisans in Syria. The best silver jewelry uses sterling silver which is 92.5% silver.
No, nickel silver and sterling silver are not the same value. Sterling silver is a precious metal composed of 92.5% silver, while nickel silver is an alloy of nickel, copper, and zinc that does not contain any silver. Sterling silver is typically more valuable than nickel silver.
...If it is nickel silver it contains no silver. It is rather an alloy of nickel and copper to create the look of silver.

Yes. they mixed nickel and iron to make the metal last longer and improved there after.
Not even close, Nickel "silver" has no silver and is a copper alloy. It simply looks slightly like silver. Items might be silver plated though. Nickel silver, also called German silver, is an alloy of approximately 60% copper, 20% nickel and 20% zinc; it doesn't contain any silver. The nickel gives it a shiny, silver appearance.
No, nickel silver is a safe material for making teapots and is not toxic. However, some people may have a nickel allergy which could cause a reaction if they come in contact with nickel silver. It is always a good idea to check with the manufacturer if you have any concerns about the materials used in your teapot.
There is no silver in a 1964 nickel.
EPCA is silver-plated nickel silver. Nickel Silver is a copper alloy (CA) mainly that is mixed in varied amounts of nickel and zinc. The higher the nickel content, the higher the quality of the nickel silver. Nickel Silver is also referred to as German Silver, Paktong, or Alpaca Silver (Mexican Surname). Nickel Silver is a highly stable and robust alloy composed of mixed metals with the formulation of 60% copper, 20% nickel and 20% zinc but does vary to some degree based on the manufacturing unit.
