After years of checking my change, I finally came across the "W" quarter that's eluded me all this time! They really do exist.
I have 2 now: American Samoa I paid $20 for, and Kansas I paid 25 cents for lol. Still looking for the other 8. They can't all be found yet.
Nice eye... I've only found two. I just check pocket change and Most of them look like W's till they don't
