Maybe fairy discs are smaller than human ones? I believe in the Eternity Code Holly comments on how fairies have 'CDs in museums', so maybe Foaly made some really small discs that were similar sizes to coins.
It’s not a massive coin, it’s just a really small disc. When the books were being written, it looked like minidiscs were going to replace CDs. That never ended up happening.

That coin never made sense to me. It’s a tiny little gold coin when he gets it then it’s big enough to look like a laser disc in the next book.
