½ Penny - William Callister Bank Token Coinage - ½ Penny (1⁄560) [gelöst]

Hi everyone

Shouldn't this be 1/480

24 x ½ Penny = 1/-
20 x 1/- = £1

24x20 = 480 ½ Pennies to the pound.

Or have I completely lost the plot??

 That page is correct. In this Search 

https://en.numista.com/catalogue/index.php?e=ile_de_man&r=PENNY&st=147-150-149&cat=y&im1=&im2=&ru=&ie=&ca=3&no=&v=&a=&dg=&i=&b=&m=&f=&t=&t2=&w=&mt=&u=&g=&c=&wi=&sw=&o=y 

 there is this for example [1 Penny (1⁄280)] 

N#86315 

 and in that Search is the heading for that section [which includes your coin] 

‘14 Pence = 1 Shilling • 20 Shillings = 1 Pound’ 

as the Isle of Man, at that time, was different than England for currency. 

 Also, hello to a fellow 2011 member. 

Many thanks ZacUK!  That never even crossed my mind.
