Out of curiousity (and I'm not sure if this is public information or not... if it's not, I apologize) - how does nationals know who the badge belonged to? I mean, say I saw an SAI badge at an antique shop, bought it, and sent it to your nationals, and a whole bunch of other people do the same. Then, one day, Lisa Legacy pledges, and wants to wear her grandmother's pin. How does your nationals know who each pin belonged to, if it was bought out of a store? Does that make sense?
