I just made a spreadsheet to track my Washington collection, and including regular business strikes, proofs and silver proofs there are, as of the end of 2013, 490 different Washington's. Holy crap.
Let's see some pics of what you've got filled! I like Silver Washingtons, but I think a lot of people find them too boring. Early clad are fine with me, but anything after the 90's is junk IMHO. Flat and look like they were designed with an etch-a-sketch.
Silver WQs (non-bullion) might be the most common coin I have kept in my collection with perhaps two dozen pieces still there.
