How many years will it take to save 1 billion pennies?
Well, you need to grasp the concept of just how big a billion is. Did you know that 1 Billion seconds is equivalent to over 31 and a half years. So even if you saved one penny every second, it would still take you 31 years! In reality it is not likely there anything like that number of pennies in circulation, but in theory it would take you a very long time.
What is normal size of pennies 15 years old?
15 year old pennies are essentially the same size as those minted today. You'd have to go back to 1857 to find pennies that were significantly larger.
How many dollars in 1000 pennies?
There are 10 dollars in 1000 pennies since each dollar consist of 100 pennies, we simply divide 1000 by 100 to get amt of dollars in 1000 pennies
How long do coins last?
It depends very much on what the coins are made of and how much use they get in comparison to other denominations. For example, in the US pennies tend to stay in circulation for about 10 or 15 years on average, but because they're low-value they tend to be stuck away in drawers, lost on the streets, etc. Quarters are more valuable but get a lot of use so they also tend to disappear from circulation after about 15 or 20 years, although it's not unusual to find some from the 1960s. The new brass $1 coins get less use and are expected to stay in circulation for 30 to 50 years. It also depends on the coin's design. When designs are changed some people begin to save the older designs so those coins may disappear from circulation a bit faster. By contrast, before England switched to the decimal system their penny had essentially the same obverse (front) design for well over a century. Nothing special stood out and old ones stayed in circulation, sometimes for 75 or 80 years.
What does a proof penny look like?
If it has not been handled, it will be bright and undamaged. Since they are struck on polished blanks several times with controlled pressure (coins for circulation are struck more in the manner of hitting it with a hammer) they should have reflective fields (empty space around the design) and well-defined details. Some years can be identified simply by an "S" mintmark because no circulation coins were struck in San Francisco.
