Playing the numbers game, there should be a bigger premium on bicent. halves than quarters, by MULTIPLE times, but there are more bicent. halves in circulation than quarters (doesn't take a genius to figure out why).
People DEFINATELY take the quarters out of circulation, and at quite a big pace. They are by no means hard to find if you go through boxes of quarters, but harder than finding halves in their own boxes.
It would hurt to save a roll or two of them for your kids or grandkids when they are even harder to come by and therefore worth a little more of a premium.
I have two rolls of them now, and am debating whether or not to keep anymore I get or release them back into the wild. Techincally by taking more and more out of circulation I am increasing the value of the ones I already have, so perhaps I will continue to take them and hoard them and hope others do the same.
