Does anyone know how much a used ps1 game named brave fencer musashi would be worth if it worked perfectly?

there is no scratch damage, has the manual but not original case, no freezing during gameplay, and no distortion what so ever. So other then being used once and not having the original case it works the same as a new one, i'm just wondering how much it would be worth cause a site i went on said new was 197$$ and another said new was 50$$ so i'm really confused what the used price could be set at... so if you can help please respond thanks
