I have 3 keepers and 2 traders, and I have been doing this for 8 months now.
Actually I stopped counting after 1000 I was getting too depressed, but the worst part is me and the missus collect almost the same thing she copies me cause she's jealous, so we have almost two of everything.
She mainly collects metal pins with pointy sharp backs on them, or anything with any Disney Character, Disney personnel, Imagineering, Disney movies, Disney parks, attractions, building, resorts, landscape, Euro Disney,
Disneyland, WDW, Disney Paris, Tokyo, TDS
.. and anything else that I might want or find on a lanyard.
And now any Arizona Diamondbacks pin as well.
