Coins of Henry VI 1422-1461 (first reign) - the 'Groat', the Penny, the Half Penny, and the Farthing were all silver coins. None of these coins showed a 'denomination'. A number of these coins are 'clipped' or worn. How can you tell which coin you have?
1430-31 - 1 Farthing = 0.24g / 10mm 1422-30 - 1/2 Penny = 0.60g / 14mm 1422-30 - 1 Penny = 0.88g / 17mm 1431-33 - 1 Penny = 0.92g / 16mm 1454-61 - 1 Penny = 0.99g / 17mm 1422-30 - 1/2 Groat = 1.92g / 21mm 1422-31 - 1 Groat = 3.64g / 28mm 1431-33 - 1 Groat = 3.44g / 27mm http://en.numista.com
Easier is if you have the Spink Year book - the pictures are all printed actual size so you can quickly see which fits best to your coin. Even when clipped it is obvious which picture best fits each coin.
@DallasCoinsNThings Thank-you. I appreciate the help. I couldn't find that scale. @PaddyB I DO have the Spink Year Book (1998 and 1974) and I suspected that might be the case, but I couldn't find a reference to that (in a hurry) so thank you for confirming it. My 1831 William IIII 'Farthing' just turned into a 'Half Penny', (even though it is not illustrated in Spink - too big for Farthing, too small for Penny). Unfortunately my 1836 William IIII Shilling didn't turn into a Crown. (See, "As you live, so you learn") Thank-you, again.
