I collect videos and music on old formats, I have one LaserDisc, 54 VHS tapes, 64 Audio Cassettes, and 6 Vinyl Records (on the "modern" disc formats I have 136 DVDs, 16 Blu-Rays, and 26 Music CDs (probably more in our household, I've only counted my personal collection so far)).
I have various other vintage electronic goodies in my possession, they include: four CRT televisions, four VCRs, a 4:3 15" LCD television, two film cameras, a Hi8 Camcorder, a mini cassette voice recorder, some game consoles, a CD/cassette boombox, etc.
My mom collects all kinds of fiesta-ware, poison bottles, hummel figurines, and old posters.
If anything else comes up at the top of my head and/or I find some pictures, I'll see about adding more to the subject.
