Hi duran,
Does lira here represent "pound sterling"?

Yes, as you think, it is.
pound=lira
penny=kuruş
In Turkey; 100 kuruş=1 lira
In England;100 pence=1 pound

Thanks, duran.

Actually, what I intended to ask was whether it stands for the British currency.

As "lira" can also be the currency of many countries (including Turkey; it was several years ago also the name of our currency).

If I translated this sentence into Hebrew, I'd write "pound" or "Lira Sterling", in order to make it obvious for the reader that we are dealing here with the British money. Also, I would write "penny" rather than "grush" or, to be more precise, "agora", which is the Hebrew for "kuruş".

I also wrote it as " Kaç peni bir pound yapar?" Many people don't know what " penny or pound" mean. So I wrote it both in Turkish and in English.But I wrote "penny" as "peni" for being understood by Turkish readers. Didn't you read it? İf you want, let me correct it as "penny" Good night.

Oh, then it's OK.
I only now saw your other sentence. I do agree that it should be written as you wrote it, "peni", as Turkish is a phonetic language.

Thank you, my friend.
Good night.
