Introduction:
GB & Ireland copper pennies (1825-60) are very sought after by collectors. They are often found in attic clearances and car boot sales in Ireland. The comparatively soft metal results in few coins surviving in higher grades. Many varieties exist and the main ones have been listed below.
William IV
William IV became king in 1830 at age 62 after the death of his brother (George IV), who had no surviving ‘legitimate’ heirs. Dubbed ‘the sailor king’ for his naval service in his younger years, William had not expected to be King. William did not marry, due primarily to the Royal Marriages Act of 1772, which forbade decendants of George II from marriage without consent from the monarch, or privy council.
- William did have a ‘de facto’ relationship producing many children, none of which were considered legitimate, so had no claim on the throne.
- Victoria thus became queen.
