The Royal Mint advises that coins are expected to have a life span of 30 to 40 years.
All predecimal British coins have long since been withdrawn from circulation and demonetised. The decimal Half (New) Penny was demonetised in 1984. The larger pre-1990 5 Pence coins were withdrawn from circulation and demonetised in 1991. The larger pre-1991 10 Pence coins were withdrawn from circulation and demonetised in 1993. The larger pre-1997 50 Pence coins were withdrawn from circulation and demonetised in 1998. All other British "Pence" coins are still legal tender.
If you got the coins in your change, they are worth whatever is inscribed on them. The Royal Mint produces many different commemorative coins each year. Some are identical to the general circulation coins, but are packaged as "Mint Uncirculated" or "Proof" coins and are usually issued in year sets. As long as these coins remain in their original packaging, they are worth more than face value. Other coins are minted from precious metals and will be worth at least the bullion value of the precious metal, plus some. As long as these coins remain in their original packaging, they are worth a lot more than face value.
it lasts about a few hundred years or so onNot really ...According to the US Mint, most American coins stay in circulation for about 30 to 50 years. Pennies get more use and are more likely to be lost or put away in jars due to their low value, so they go out of circulation somewhat faster.Other countries have had different experiences. For example, England used the same size and similar design of its pennies for about 250 years and fewer Britons collect coins, so some of their pennies stayed in circulation for a century or more.Of course when coins are replaced (e.g. modern British decimal pennies replaced the old ones in 1971, euros replaced marks/francs/lira/etc. in 2002, and so on) the lifespan of those older coins can be quite short.

The average amount of time that a nickel stays in circulation is 25 years. Any coins that are no longer fit for circulation can be redeemed at the United States Mint.
Circulation life of modern coins is 30 years with most lasting longer.
The larger pre-1991 5 Pence coins were withdrawn from circulation and demonetised in 1991. So, unless they are part of a Proof or Uncirculated mint set or are individual Proof or Uncirculated coins and in absolute mint condition, they have little or no value. A British 1968 cupro-nickel 5 New Pence coin (Elizabeth II), uncirculated and in absolute mint condition could fetch up to £0.20 GBP. A reputable coin dealer will be able to give a more accurate valuation.
Your description is applicable to every British coin issued in 1979. On the same side of the coin you read "New Pence", there will be a number indicating "how many" New Pence. The 1979 British 1/2, 5, 10 and 50 New Pence coins have long been withdrawn from circulation and have little or no value unless they are in mint condition, and even then, not much. The 1979 British 1 New Penny and 2 New Pence coins are still potentially in circulation, so are worth 1 and 2 Pence respectively, unless they are in mint condition, and even then, not much.
No, at least not for a long time. Many of the coins never saw circulation in the first place, so there's no shortage of quality specimens. And the later coins will still be minted, just in lower numbers specifically to be sold to collectors.
An alloy of copper and nickel produces a strong and durable coin that is relatively cheap to produce, is resistant to corrosion, and has a potentially long serviceable life span with normal use. The most common ratio for British cupro-nickel coins is 75% copper and 25% nickel, which surprisingly gives the coins a silvery appearance.
Pure copper, silver and gold has not been used to make general circulation coins for a long time, but for many years, the value of a coin was determined by the metal it was made from and its weight. British copper coins changed to bronze, which included a large percentage of copper, in 1860. British silver coins were gradually debased from 1919/1920 and changed to a copper nickel alloy from 1947. Copper was a relatively cheap and durable metal to make coins from once, but became much too expensive, even as part of a bronze alloy. In the early 1990's, all British bronze coins were subsequently made from copper plated steel. Silver was used to make coins of a higher value and the value of the coin was reflected in the diameter and weight of the coin, but silver also became too expensive.
Point 1 - Sixpences converted to 2.5 Pence at the conversion to decimal currency, Shillings converted to 5 Pence.Point 2 - Banks are under no obligation to accept the old 1/2, 5, 10 and 50 Pence coins, much less any pre-decimal coins, and "might" only do so if you are an account holding customer.If your pre-decimal coins are in good condition, you might get more for them from a coin dealer or collector.
