What could リル mean in this situation?


I'm reading a children's story called きつつき商売. Here's an excerpt:

> 『音屋』
>
> それだけでは、なんだか分かりにくいので、きつつきは、そのあとにこう、書きました。
>
> 「できたての音、すてきないい音、おきかせします。四分音符一こにつき、どれでも１００リル」

I'm assuming リル is some sort of currency, but all of my normal internet
searches aren't helping me figure out specifically what it is. What could リル
mean in this context?




Yes, it seems to be the currency the woodpecker is selling its sounds for.

It seems other people where wondering the same thing, including native
speakers so this is definitely a word made up for the story, and it isn't made
very clear in the story either.

See [this Q&A](http://oshiete.goo.ne.jp/qa/1212795.html) where someone asked
the same question (and how to read `野ねずみ`).

talks about this story, and if you do a quick search for リル on the page you'll
find several people in the comments wondering what this currency may actually
be, how much it's worth...
