Numista letters next to year of issue meaning? [Risolto]

ive a few coins from the isle of man and  next to the year of issue there are two letters eg .1987 AA  or 1987AB what does the letters mean ?

Hi,

The letters are mint mark letters that are on the coin. They are small stylised letters on the coin. Most commonly found are AA.

so there are AA on the coin somewhere? where abouts are they usually ?

See here: AB letters at the right hand base of the building. They are in different places.

one of my friends just pointed it out to me on one of the boat 2 pence. really hard to make out on some of them !  noticed on some of the listing on here now that they mention where the mint mark is on some coins.   some dont. Ive had two differnt magnifying glasses trying to spot them . maybe a mint mark location photo might be an idea in future on here for people like me ha

just ordered a little pocket microscope off ebay . see if that helps ! thanks for the help

A loupe is always a good idea. For mintmarks, Spanish star dates and privy marks.
