While I missed that mark by a small margin this is a collection of what I managed to wrangle for $100. This is not a collectors lot of locks and all were obtained by perfectly legal methods. They were all either found, gifted, purchased online/offline traded for or already owned and dug out of the garage. I have keys for about 1/2 of these and this bunch gives me a wide variety of locks to play with at my leisure and the ones I don't have keys for it gives me an excuse to learn to impression. I took more of a quantity over quality approach so I could sample the spectrum. I ended up with some decent locks in the process.

Some Schlage locks

Arrow Practice core, Misc Schlage and some cam locks. I also picked up a Vans Vending lock because it looked really cool.
All in all I am pretty pleased because now I have no excuse not to see what different locks and keyways feel like. I am going to keep amassing and plan to do another try at $100 for $100 see if I can hit the mark. I have several out on loan that are not pictured but will do so when I get them back.
