Hello Kitty Coin Purse

Me and my mom were going through a big tub of old photos and I found my Hello Kitty coin purse. It's a bit dirty but no holes. It's made of vinyl with a metal closure and a metal keychain with a cute rainbow flower. I think this theme is Hello Kitty Mermaid.

 

If you know anything about these little coin purses let me know. Is it rare?
