The Eire (Irish) 20 Pence coin minted from 1986 to 2000, is made from a nickel/bronze alloy and are not plated.
Any discolouration (browning or yellowing) will most likely be due to light tarnishing of the coin.
No. It is all steel with copper plating.
No, there is no lead inBritishcoins.Here is what the British coins are made of:One Penny - Bronze (1971-1992). Copper-plated steel (1992-present)Two pence - 97% bronze, 2.5% zinc and 0.5% tin until 1992. Copper-plated steel from 1992 to presentFive pence - Cupronickel (nickel-plated steel)Ten pence - CupronickelTwenty pence -CupronickelTwenty-five pence -Cupronickel (nickel-plated steel) - these are no longer madeFifty pence -CupronickelOne pound - Nickel-brassTwo pounds - Inner:Cupronickel. Outer: Nickel-brassFive pounds -Cupronickel (legal to tender as money but intended as souvenirs, therefore not seen often)
The lowest denominations are magnetic (attracted to magnets).The current 1 pence, 2 pence, 5 pence and 10 pence coins are nickel-plated steel.(The change was made to 5 and 10 pence in January 2012.)
British 5 Pence coins are made from cupro-nickel. If you have a bronze 5 Pence coin, it has either been plated or it is a novelty coin. Either way it is worthless.
British copper plated steel 1 and 2 Pence coins were introduced in 1992.
There is no British 2 cent coin. The Brits have a 2 Pence coin, which is currently the second lowest denomination British coin in circulation. Up to 1992 they were made from bronze, from 1992 onwards, they are made from copper plated steel and are 25.91 mm in diameter.
No - it just looks nice. When an item is electro plated, the plating material is very thin - less than 0.01mm - so there is hardly any volume of gold. So even though gold is expensive, a gold-plated item is worth just a few pence (cents) more than the item would be without the gold. This is ok for inexpensive jewelry, but do not be fooled into buying any gold or silver 'investment bars' or coins that are plated or described as '100 mills' or 'HGE' ('heavy-gold-electroplate') - these are just lumps of base metal (such as steel or copper) with no real value.
If you refer to the British 1 Penny and 2 Pence coins, they are currently made from copper-plated steel.
No, not unless the item that is plated is itself worth anything (such as a gold-plated Rolls Royce).When an item is electro plated, the plating material is very thin - less than 0.01mm - so there is hardly any volume of gold.

The lowest denominations of current UK coins will be attracted to a magnet. In the UK, copper-plated steel was used for 1 and 2 pence coins beginning in 1992, replacing their bronze predecessors. Steel, being an alloy of iron, can be attracted to a magnet. The 5 and 10 pence coins were changed to nickel-plated steel in 2011. These coins will also display magnetic properties. In 1998, some 1 and 2 pence coins were issued in bronze (not magnetic).
It depends on the volume of the gold that is plated on the jewelry, but when an item is electro plated, the plating material is usually very thin - less than 0.01mm - so there is hardly any volume of gold. So even though gold is expensive, a gold-plated item is worth just a few pence (cents) more than the item would be if it did not have the gold. This is ok if you want to buy inexpensive jewelry, where the main thing is whether it looks good, but you won't be able to sell it for any money.
A 1 pence coin is a conductor because it is made of metal (copper-plated steel) which allows electricity to flow through it easily. Conductors have low resistance to the flow of electrical current.
