Should I Dump My State Quarters

IF you need the money, dump them. Same with the baby dollars. Neither will ever make you rich. I have a few Whitman Albums full of those Quarters and when the started the Park stuff, I stopped. If you don't need the money, remember that in about 100 or 200 years you could sell them for a little over face value making keeping them worth something.
Not sure why I keep mine except I just don't need the money right now. I fell for that keeping all the Bicentennial Quarters back in the 70's. After over 30 years I found they were at least worth a Quarter.
As to those baby sized dollars, I don't even try to collect those at all. So many do that even in 10,000 years they will be worth about $0.99 + or - a little.

Thanks for the input,everyone! I think that I'll dump them all. I really have no need for them. Once the US goes back to having one quarter design each year, then I'll go back to saving a BU P & D of each.

I'm not overly keen on them but am keeping the folder I have with them.

You may want to reconsider. The current program will, at minimum, run until 2021. The series may (and probably will) be extended by the Secretary of the Treasury to 2033. I do not know about you, but I am in no hurry to get to 2033.
