The copper nickel 5 pound coins usually are worth a small premium over face value if uncirculated. If uncirculated it might be worth 10-20 pounds if you're lucky, if it has circulation damage, its value falls to 5 or 6 pounds. 2007 isn't a particularly rare year nor a particularly desirable year for 5 pound coins.
There are no British general circulation Pennies made from cupro nickel, from 1860 to 1967 they were all made from bronze. If you have a cupro nickel penny, it has been plated and is worthless as a collectible.
All 1958 British coins will have a face value on them somewhere. British coins minted in 1958 include - Cupro-nickel Halfcrown (Two Shillings and Sixpence) Cupro-nickel Florin (Two Shillings) Cupro-nickel Shilling (English reverse) Cupro-nickel Shilling (Scottish reverse) Cupro-nickel Sixpence Nickel-brass Threepence (12 sided) Bronze Penny Bronze Halfenny Bronze Farthing (quarter Penny) The 22 carat gold Sovereign would be the only coin that has traditionally never had a face value on it.

The British cupro-nickel 23.5mm 5 Pence coin changed to a cupro-nickel 18mm 5 Pence coin in 1990. The larger pre-1990 5 Pence coins were withdrawn from circulation and demonetised in 1991.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.
If the coins are current, there are laws that will prevent you from damaging them, and they are still worth face value. If the coins have been demonetised but are still in reasonably good condition, a coin dealer may be interested. If you a looking at selling cupro-nickel coins for their scrap metal value, don't bother, you would need hundreds of kilograms of them to make it worthwhile. Mints use the cupro-nickel alloy because it makes a "cheap" and durable coin.
One Pound British in 1860 had the purchasing power of about £63.10 GBP in 2010. This is an approximation based on the value of the pound in 1860 and the value of the pound in 2010, factoring for inflation.
Assuming you have cupro-nickel British Florins in circulated but reasonable condition, the individual coin values might range between £1 to £5 GBP. A reputable coin dealer will be able to give a more accurate valuation for the set.
These coins have only just been released into circulation 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 are worth 5 Pence.
