Everything above is true.
British pennies and halfpence were minted in huge numbers between 1860 and 1967. Some years had as many as 100 million coins minted.
They circulated throughout the UK and in many colonies until the mid 20th century. Here in New Zealand we had them until 1940, Australia had them to 1911, South Africa until 1923, and also ina few other places like Malta, Gibraltar, Ireland, Seychelles, Mauritus and various southern african colonies and the pacific islands as well.
As a penny had the buying power in 1900 of around 50 cents today, they were in everyones pockets and saw heavy usage. Hence with the exception of a few dates and varieties like 1933, 99% of these coins are worth melt value only (The copper in a penny is worth around 6 US cents) and nominally at facevalue (0.4166 British pence).
Pennies before about 1900 are worth some money in VF or better conditon ($10 in VF to say $50 in UNC for most dates). Coins from George V 1911 - 1936 are worth maybe $2 or 3 in VF and $20 in UNC for 1910s coins but only $2 for 1936 coins.
George VI and Elizabeth coins are worth maybe $1 each in UNC condition and nothing in other conditions.
Your 1919 coin is in G - VG condition, practically the minimum possible condition for a 1919 coin which should be at least Fine.
Sorry the news is not better.
UNC means no wear and bright lustre with pinkish mint bloom.
Loving Halfcrowns. British and Commonwealth coins 1750 - 1950 and anything Kiwi.
If it's round, shiny and silvery I will love it.
