It's really simple.

Your best bet is to acquire rolls from multiple sources. Spot check a roll from
each source and if you find anything good or anything promising then go back
and see if you can get more. Just dump any of these searched coins into cir-
culation if you have plenty of rolls. Now search a roll from each discreet batch.
If you don't see anything good then set the rest of the the batch aside to save.
If you do see something then open every roll in the batch and save the nice ones.
When you're done you'll have a little pile of choice and gem coins and a stash of
rolls. Decide how many you want to set aside and pull out the worst rolls to spend
if there's an overage. Nicer rolls will be much easier to sell.
Remember that other people may be saving this coin extensively too, so if it doesn't
go up in three or four years then take them to the bank. Don't allow your money to
depreciate. If they do go up be sure to take at least a little profit. You can use this
for other coins that you think are too cheap or to stash more coins. Don't be too
surprised if dimes are being saved in insufficient numbers the last few years.
While those bicentennial coins were saved in massive numbers very few
people were paying any attention to the quality. They were mostly fairly
good but there were almost no gems. While the typical bicentennial quar-
ter is distressinly common today, gems are scarce and an important type
coin. They can sell for hundreds or even thousands of dollars for superb
coins.
