Are the NPC pins going to be rare? My friend and I were in a trade room and this guy asks to trade and says the NPC pins are going to be rare so he wanted my friend's polyneisan pin in exchange for 2 NPC pins. Are they going to be rare or is this guy cheating my friend out? I asked Host Phinny when I was playing basball but got booted!

So please help.
When in doubt, see if there's a Community Leader around in the same
room you're in. If you don't see one, trust your gut. Anyone claiming
the items they have are "rare", and they are really PUSHING you to trade,
close out a trade window.
If there's no leader around, try to ask around in a public room, but using
the OTHER guy's offer as the test. "If I offer a Ned and Yeti pin for
a Polynesian pin, is that a fair trade?"
This way, other people will be more than honest and tell you that you've
made a "horrible" offer. And that will tell YOU that the other person was
trying to cheat you.
