I was actually lucky enough to get one of these pins. I was at a convention for CliniVision, an information system that is hospital based. We were given a tour on May 19th through the Disney Institute, titled Inspiration Through Walt's Eyes. It is given to corporate customers only. After the tour, we were all given these pins. There were 150 of us on the tour so that is how many were given at that time. Our guide told us we were the first group to get them. He said they used to give out pins that were developed for the 100 year celebration but finally got one made specifically for that tour. I also happen to be a Disney collector, so was thrilled to get it but many on the tour really didn't care about it. He had to explain how valuable they were going to be to the group and told everyone not to trade for just anything. This happened to be the same guide we had on a Backstage Magic tour last year. (That tour also has a great pin.) I asked how often they give the tour and he said about once a month on average, sometimes a couple of times a month and occassionally just every other month but on average once.
