Hey guys, Once they release a HM set, do they ever "retire" it and stop putting a set on the boards/lanyards ? And how long do they stay ? On a trip a few years ago I saw a ton of the older t-shirt Hidden Mickeys which I thought had to be fake...until I was searching for a specific pin for a different set, and very nice cast member whipped out a stock bag of hidden mickey's she had behind the desk and I noticed the t-shirts were in there with some current pins. So, what are the chances of finding older real pins ? Or if I find a HM pin past X number of years old should I assume it's fake because Disney no longer puts them out ?
