Pence is the plural of Penny, so you have One Penny or, Two Pence, Five Pence, Fifty Pence, etc. From the introduction of British decimal coins in 1968, the new currency was designated as "New", ie. 1 New Penny, 2 New Pence, etc. until 1981. From 1982 onwards, the "New" was dropped.
The British New Penny coin was first issued in 1971.
The decimal New Half Penny and Half Penny coins were last issued for circulation in 1983 and were withdrawn from circulation and demonetised in December 1984. 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 1981 bronze Half New Penny (Elizabeth II), uncirculated and in absolute mint condition could fetch up to £0.20 GBP. A British 1981 bronze Half New Penny (Elizabeth II)(Proof FDC), uncirculated and in absolute mint condition could fetch up to £1 GBP. A reputable coin dealer will be able to give a more accurate valuation.
I can't find any listings for a British penny with that date. Could you post a new question with additional information, including any wording on the coin and a description of the image on the side that doesn't have the King's picture? NEW : One cent, it does not matter what year it is. A penny is still a penny.
The oldest British Penny potentially still in circulation would be the 1971 New Penny.
The British "New Penny" was first issued in 1971, along with the Two New Pence and the Half New Penny. From 1982, the "New" was dropped and the coin was known as the 'Penny" again. This is true for all British decimal coins, the word "New" no longer being used from 1982.
The structure on the reverse of the Penny is a "crowned" portcullis (or gate).

The reverse of the new British Penny shows part of a composite design depicting the Royal Shield which is able to be seen when one of each British denomination coin is positioned correctly.
U.K. coins with the denomination "new penny" were only issued from 1971 to 1981. Please check again and post a new question.
