Too many to count. My old neighborhood would organize an annual garage sale, and I'd always end up dragging home any bike I could find.

The Miyata I found at an ARC for $30. I wish I hadn't sold it. The Huffy I found at a Garage sale, bought for $5. The AMF for $10.
I Don't remember where I found this murray. It was fun to ride and my size, but I already had better 3 speeds. I kept the basket.
Sold this murray when I moved from Savannah, because I didn't think it was worth shipping:
This (AMF) All-Pro turned out to be too big for me, but I had already driven way out to pick it up, so I took it home repacked the bearings and sold it on.
I could dig up pictures of the rest, but I'll just list them in no apparent order:
JC Penney his/hers "matching" pair (men's was a huffy, woman's was an AMF, for some reason)
Gitane Sport Deluxe
Huffy Omni 10
Lady's Raleigh Sports
Western Flyer Freeway Flyer (AMF)
Wards 3 speed (Executive)
Sears Free Spirit (huffy) lady's 10-speed
Sears 3 speed (huffy, was my commuter for a year)
All-Pro 3 speed (huffy, was my commuter for two years)
Schwinn Suburban 5 speed (bought and refurbed for my step dad who probably rode it twice, sold when he divorced my mom after he decided being a drunk was more his thing than being a decent person)
Sears Free Spirit lady's ten speed tourer (made in Taiwan)
Some Japanese made 10 speed, I cannot recall the maker of.
Columbia Middleweight (coaster brake had cracked shoes, too much of a hassle to track down to repair such a worthless bike, sold to an old lady as a lawn ornament)
Columbia Sports III (lady's late 70s)
Phillips Lady's 3 speed (early, with oil port in the BB; parted out, was in terrible condition).
Hawthorne pre-war ballooner
Parted out a couple of other old bikes, from what I remember a 70's Columbia Gold Crest, a 63 Columbia 3 speed, a "Senator" 10 speed, a Steyr-Puch.
Probably a couple more I am not remembering ATM.
Most of these I sold for about $30-$60
