Quoted from rai:Like as Stern made SW comic edition. Way cheaper than designing a whole new pin. They could make 600 SW pins (or some number) and people will buy them. I know quite a few people here just picked up SW comic. Those sales could have gone to secondary market but instead went to Stern.
Think of how long it takes another company to sell 500 pins and Stern did it with SW like it was no big deal.
I wonder why they did not go the route of slightly new version like Star Wars versus a second vault.
