The value of a threepence – in this case we are talking about the 12-sided, brass 'thrupenny bit' that was produced during the 20th century – varies depending upon the year it was minted, and the rarity of that year's issue. Therefore, it can be anywhere between a few pence and quite large amounts of money.
