Pins are our way to pass the time on lines We see Cm and other guests and see their pins. Our kids and myself try yo get certain characters myself a Toy Story nut as an example.
VALUE I am sure there are some in the pins but no many are in it for that just seem to like the series and try to collect them all.
There are websites out there to help you disney has a link as well
The cost of pins in the parks is incredible and if not careful before you know it you could be up to a hundred bucks for about 7-8 pins. The outlet malls have reduced pins but still go for 2.50-3.00 a pin
EBAY if you can find them sellers sell them for about a buck a pin. We judt bought a for our next trip.
The new vinylmation characters are being hyped as the next big thing and some think they may replace the Pins but everyone I spoke to from Disney say Pins are here to stay.
Have fun with them
