Did some of the original Nintendo games come with missing metal contacts, i.e. produced that way? I already tried looking on Google and on here but couldn't come up with anything I needed, only how to clean original NES contacts. I'm almost 100% sure many games were produced that way, but I've seen a video game retailer recently refuse NES games because they didn't have all the contacts, and just today someone asked me if a particular game had all its contacts. I have a few hundred NES games and they all work with or without the supposed missing contacts.
