A friend of my husbands gave us a bag of Disney pins that his wife collected over the years...she tried to sell them, but didn't have much luck, so decided to just give them to us, because she knew that my daughter and I collected Disney pins. 
We are heading to WDW in 23 days, and it is very overwhelming to look these over and decide which would be good for trading...I've always just collected those pins that I personally liked, but she has given us some LE pins, Cast Member pins, Event pins (like Valentines Day of a certain year), and a couple of DVC pins.
Can someone please help us understand which we should definately keep due to value or potential value versus those that would be good traders?
Any advice/help would be appreciated!
Thanks!
