Have any new "extra leaves" Wisconsin quarters been found lately?

I went to a coin show last weekend and saw 2 raw lower leaf Wisconsin quarters with a price of $240 each. And it made we wonder If people haven't found any more? Doesn't it kind of look like the ones found already are going to be the only ones? With the internet and all the news reports about them I would think a lot of people were looking for them and if somebody found a bunch of rolls in a city somewhere wouldn't somebody say something about it by now?

kept quiet if there had been another release. It's probable that well over 90%
of the total issue of D- WI 25c has been released and it is becoming improbable
that there will be more. Coins which are made together tend to be released to-
gether not only geographically but also temporally. For whatever reason, it is be-
ginning to look like these dies had very short runs.
Here's a warning parable for coin collectors...
