I bought a coffee can full of keys 25 year ago expecting to use them in some kind of industrial craft and here I am 25 years later and I haven't done a thing with them.  Lucky you.  This collection of just over 300 keys can now be yours.  I sifted through them and found a few clock parts and other things that aren't keys but most are legit keys. There are keys for wind-up toys, clocks, bikes, skates, skeleton keys, luggage, door, car and whatever you can imagine a key can be used for.  Please study the photos carefully to see if this is worth your while. I'm sure there's many treasures to be found here.  Conditions vary but I didn't see anything obviously broken.  See calculator to ship these goodies.
