Hello there,
Recently I have discovered that 2 Pence 1991 Isle of Man coin has two mint mark varieties.
1) At the bottom part of the coin, as seen in Numista entry:

2) More to the centre of the coin as seen in this link:

and on the coin in my collection:
Could we please update the catalogue the reflect this?
