Japanese DC 3rd Strike worth something?

I have the Japanese version of 3rd Strike for the Dreamcast. The jewel case has a crack (stupid me for putting it in my suitcase) but the disc and booklet are fine.

Does anyone know if this is even worth anything?

they got it at a used game store by my house for like 10 bucks. you should check ebay or something to see about how much you can fetch
