Any coin with a "genuine" minting flaw would have some value, above the usual, as a collectible coin.
Genuinely flawed coins are not necessarily known about or documented until somebody turns up with one, since they are an "accident" of the minting process, and have escaped detection during quality control at the mint therefore, a valuation cannot be anticipated.
A reputable coin dealer should be able to identify and confirm the coin as genuine and make a valuation.
The problem with one-off flaws is that their value depends on the significance of the flaw but as one-offs, a dealer's opinion can only be speculative. These do appear from time to time on eBay and if your coin is similar to one that has sold, this will be an indication of the value of your own coin.
These are never documented or catalogued unless they are found in numbers, even small numbers.
You do not give the nature of the mis-strike.

Flaws and errors on coins should not be confused with mutilation or mangling of the coin.
The "face value" of a coin is whatever is inscribed on it, hence the term "face value". The face value of a 10 Pence coin is 10 Pence.
Such a coin does not exist. The 10 pence coin was first issued in 1968.
Such a coin does not exist. The Irish 10 Pence coin was first issued in 1969.
Such a coin does not exist. The Eire (Irish) 10 Pence coin was first introduced into the currency in 1969.
The value of the copper in a 2 Pence coin would be significantly less then 10% of the face value of the coin at the time the coin was minted. Today, it might be a little more, about 0.2 Pence.
The 10 New Pence coin was not introduced until 1968.
The two coins are a ten-pence coin and a one pence-coin. The one-pence coin is the one that is not a ten-pence coin.
In 1944, the British used Pounds, Shillings and Pence. The British have never used cents. There has never been a British 10 cent coin and the British 10 Pence coin was first issued in 1968.
If you have a 5 Pence coin that is the same diameter as a 1988 10 Pence coin, yes, it is rare. The largest 5 Pence coin was 1.5 mm smaller than the smallest 10 Pence coin. You may have a 5 Pence coin struck on a 10 Pence blank. Any coin with a "genuine" minting flaw would have some value, above the usual, as a collectible coin.

Occasionally, the Royal mint has a mix up with the dies or the blanks used to produce coins. It is possible that the 10 New Pence dies were used on a 2 New Pence blank. If this is the case, part of the 10 Pence coin design will be outside the perimeter of the 2 Pence blank, the 10 Pence coin being slightly larger than the 2 Pence coin. Alternatively, you may have a trick coin available from magic shops.
