I have seen your request, and changed it - it is a token not coin.

I am not worried about a catalogue number - maybe someone over time will add that.
Zac,
This should be in the 'Coins' section, along with all the other currency tokens that circulated as coins in the late 18th. & early 19th. Centuries during the severe coin shortage.
Somebody had better change the section then - it currently reads
Ireland • Currency tokens (1757-1816)
and at least should be
Ireland • Currency tokens (1757-1822)
as there is yours for 1818 and another in there dated 1822.
I have asked the referees to hopefully change the end date -
then I will make a request to move the token into there,
together with that other 1818 token I mentioned earlier.
