Yoshi no Panepon for GB Any idea the rariity of this cart?

[Koleman-GameOn]

Looks like Yoshi's Cookie, a google search let me know its called "Yoshi no Panepon" or Tetris Attack, DMG-AYLJ-JPN. I am the manager of a video game store (www.gameoncanada.com) and I am looking to price this, just wanted your expert advice. Thanks! BTW, this is my first post, and I plan on being active here, as we do trades on old games, and maybe I can help some collectors out.

Thanks!

not a very rare game at all
maybe 3-10$ loose
and 10-15$ complete
