Quoted from kaneda:I'm betting all prices will drop because of the volume of new pins hitting the market in 2016. Not just Hobbit forcing WOZ down. GB will force WOZ down. Star Wars will force TWD down. By the end of this year, no used pin will be gaining value ala Tron LE. Maybe RZ since it's so rare. But everything else will be made until my diapers come off.
The 'new pins are coming' logic never really plays out. WOZ, AC/DC, Met, B/W pins, even some of the newer Sterns... none are dropping or are only slightly dropping and that just depends on how good the pin is.
It's actually quite impressive that the value holds for recent pins with how many are being released these days.
