In 1990 the Isle of Man issued a commemorative set to mark the 150th anniversary of the Penny Black.
The lowest value was just 1p, and came in 25 types, with the bottom corner letters ranging from A-A to E-E.
I have managed to get hold of two complete sets of these plates which are just going on the website. These are very hard to put together so they are £3.50 each set of 25, vastly cheaper than trying to complete a pane of original Penny Blacks!
