If so, they would be 3,800 Y.
Can't remember how much I paid for mine when I went to NL. But I'd brought 30,000 Y with me and spent almost all of it on merchandise! n____n'' Put some extra aside just for goodies, you will want to bring everything home, definitely. And make sure to get to the stands ahead of time to buy, certain items sell out really fast!
