I've mentioned this one before. When they came out with those Bicentennial Quarters myself and a friend started to hoard them. He eventually had a few thousand of them. I had hundreds of them too. After over 30 years at a few coin shows we attempted to sell some. Even in the highest grades all dealers just either laughed or point blank said forget it. Eventually they all ended up in the bank. Hopefully you too don't get to that point.
Yeah, I'm thinking the same thing will happen with the state quarters. By the way, what states are people hoarding. I have a D book full and thinking about making a P book. Other than that I've been keeping the 1999s.
The best bet is probably to try to put together a set of the nicest clads of each date you can find. Don't only look for coins with the least wear but for coins with the best strikes from the best dies. This will not only be an inexpensive and enjoyable challenge in itself but it will provide a good reference set so you can always compare a suspected variety to it. You'll probably find a lot of pretty interesting varieties some of which may be quite valuable some day. You'll also probably learn a lot about the distribution of coins and how they wear. You'll get insights into the economy and mass psychology. Mostly it's just fun and there isn't much you can do for less than $20 any more that can possibly compete.
