I only have 3 sets out on display in my office: 2016 Not So Scary Halloween Party villains with masks set, 2016 Season's Greetings ice skates set, and a Disneyland framed pin set (where each letter is a pin). The 2 boxed sets just sit on my desk, but the DL frame is on the wall above my door. All the rest of my pins are in the closet or on my bookshelf. I wish I could have them out on view to look at them more often.
The pins in my closet are in those Disney pin books or bags or in a box for the boxed sets or special boxed pins. The ones in the bookshelf are in 3 ring binders in various pocket pages.
For my pin collections, since the vast majority are in the closet, I take a photo of every single page so I know which I own. The only photos I didn't take are the boxed sets/boxed individual pins. I use pinpics and have an Excel file of all my pins. I love inventory lists! Anyways, in no particular order except for the photo order in my phone:
1. various Hidden Mickey sets - I don't collect all of them, but I have more than I thought because it's hard for me to not be a completist when I get 1 hidden mickey on a cast member lanyard.
2. male human leads, with a focus on Prince Philip, Prince Eric, Aladdin, and Will Turner
3. Jack Skellington
4. villain sets - this is my largest collection that take over 2 books because there are so many sets!
5. Mickey Mouse and mickey icons (mickey head shape) - When I finally organized my collection a few years ago, I never realized I had so many Mickey Mouse, so this is my unintentional collection.
6. Star Wars
7. Maleficent - my favorite Disney character
8. other individual villains with a focus on Evil Queen, Ursula/Vanessa, and Chernabog
9. Epcot 30th anniversary
10. Hollywood Studios 25th anniversary
11. occasion days, such as holidays, seasons, Mothers/Fathers Day, etc.
12. D23 exclusives - anyone else going this July? I can't wait.
13. attractions separated by DL/DCA only, WDW only, and shared
14. Pirates of The Caribbean with a focus on the redhead
15. Disneyland 50th anniversary - I love looking at all the gold!
16. various character sets - This is vague, but here are my favorites: Christmas light bulbs, Chinese zodiac, the kiss, princess filigree, La Noel de Raiponce, good luck bad luck, BATB vinylmation, Aladdin map, Disney dreams DLP, flowers pursuit, TLM character connection, as well as lots of the PWP sets and quarterly AP sets
17. Stitch San Francisco - this is probably my most niche collection
18. Frozen
19. Haunted Mansion
20. Disneyland 60th anniversary - I love looking at all the diamonds!
21. Marvel
22. everything else, which is 10 pins or less of various characters or movies, such as Fab 6, Tigger, Chip & Dale, Tinker Bell, pins that have my initials J and Q, The Little Mermaid, The Lion King, Aladdin.
I have several lanyards that I alternate wearing at Disneyland/DCA (lucky to be an annual passholder) and about once every 3 years when I can get to WDW. They are: male leads, Haunted Mansion, villains, Jack Skellington, Halloween, Christmas, Marvel, Disneyland 60th anniversary, Star Wars, and Kristoff.
This has been great reading about everyone else's collections, and I enjoyed writing about my collection.
