Lord of The Ring "coin"

So one of my friends got this coin that a guy made when he had a loose licencing agreement and made these coin. I would like some information on it like when it is in the book and what it says

Sorry if this is in the wrong place

 

Shire Post - I remember those!
Never knew he made any from Eregion though - sorry to have missed 'em.

If there's any mention at all of them, they'd have to be in some of the ancillary material. Silmarillion, Lost Tales, or the like. Eregion was old and gone by LOTR/Hobbit times.
For a translation, I think your best bet is one of the elvish language fora.
