I bought 12 pins on my cruise plus the set of 4 "mount rustmore" pins. I have them framed in one of those frames butterfly collectors use, with blue felt over it, with a family photo on CC in the middle of it.
If you are interested in collecting these for profit, check out EBay. I can tell you a limited edition premiered while I was on the Wonder and I only bought one, and later saw it for as much as $22 on Ebay. Of course not all pins get this return and your mileage may vary.
