Not Just Another Quarter Sample.
This one was heavily contaminated with old well worn eagle reverse coins. Contamination like this is necessarily the result of collectors separating coins by date. Or, at least, anyone who separates coins by date is almost certainly a coin collector. The best guess in this case since they are rolls provided by a counting house is that somebody went through a vast accumulation of old quarters and redeemed the heavily worn ones. Even if the hopper in which these separated coins were dumped was nearly empty, in order to affect an entire sample would require many thousands of coins.
Somebody accumulated a lot of old clad quarters and dumped the worn one. Some of these coins were as heavily worn as many clads were before 2012 suggesting that this hoarding probably began about 2005. Of course it's impossible to tell every anomalous specimen from random chance. The "individual" saved F's and better for the good dates and VF's and better for common dates. Starting so late it's unlikely he found any better dates better than high end VF with a smattering of nice XF's.
Also making this sample interesting is my very first W quarter. I'm late to the party but glad to have my ticket. It is a nice well made and highly lustrous 2019 Mariana Island in AU. It looks like it's changed hands about 15 times.
The rest of the coins were mostly uninteresting to most people. There was simply nothing that might go into even a beginners collection except an AU- 1994-D. It isn't a particularly nice coin because it has been beaten up a little. Because of the contamination it was only 60% post-1998 coins.
