Not So Scary Halloween Party Disney Pins

When we were down in Orlando in September, we picked up these two pins at the #NotSoScary Halloween party at the Magic Kingdom.  The Haunted Mansion one on the left has a yellow card and is marked "Limited Edition".  The Mickey/Minnie one on the right is on a purple card and is marked "Limited Release".

Have no idea what the difference is, but based on where they were located (The purple one was behind the registers and you had to ask for it and show your bracelet vs the yellow one was in the pin shop in Frontierland on a normal rack.), I'm thinking the "Limited Release" one is more rare (whatever that means!?!).

I still haven't quite gone through all the pins that the girls traded for when we were down there and because we're staying in my sister's/Equation Boy/Man's house, we don't have a good place to display them.  Thus, they're just sitting in a Parks bag on my desk awaiting for the time to go through them.
