This is not a coin made by the US mint. It's an old coin which may increase the value a little bit. The value is pretty much what a collector wants to pay. On a coin like this it's going to vary but it probably won't be very much.
A lower-value coin minted between 1845 and 1926 by and for the British Government in the Straits Settlements (now known as Malaysia).
Such a coin does not exist. The Half Farthing was issued from 1828, and only for use in Ceylon (Sri Lanka) at that time. In 1824, King George IV would have appeared on the coin. Queen Victoria Half Farthings were issued for circulation perodically from 1839 to 1856.
Please check your coin again and post a new question. Indian head cents were minted from 1859 to mid-1909.

With the exception of the 1817 15 star coin all US large cents from 1810 to 1857 have 13 stars.1824 has a very wide retail price range from $20.00 in G-4 to $165.00 in VF-20 to $850.00 in AU-50 I suggest you show it to a dealer or collector for an accurate value.
A coin from 1824 could be quite rare and worth a lot. It depends on what kind of coin it is. That is, whether it is from the US or another country, and in most cases a bigger coin is worth more. Also, the condition of the coin is very important.
