Ah, Marje: tuppence was 2 real pennies [2d]. The modern minidisc is called a two-pence [tu-pens] piece. & while the ½-new-penny piece did survive, it was a half-penny, not a proper 'heighpnee' that we grew up with.

What would be the use of finding a crooked 2-&-a-half-pence beside a crooked style!
