Allagan Tomestones

I've eventually found out in Mor Dhona the NPC who trades gear for them. Cool stuff. The problem is that I am pretty sure I've got the messages telling me I was receiving the Tomestones in a couple of DFs and in my inventory there are none. The NPC didn't show any either? Where are they stored?

They're classed as 'currency' so in the main menu bar they listed under 'Character' and the 'Currency' tab (the same page where gil and Grand Company seals are also listed).

Oww. Thanks. That's the only place i didn't check.
