1966 Topps High's - Any uncut sheets or partial sheets known?

[G1911]

I know there are as many opinions about the high series as there are cards in it. I think there is clearly a scarcity division between single prints and double prints, though there seem to be several different tiers of short prints that I'm just not seeing myself. Example, I have no difficulty finding Grant Jackson or Choo Choo Coleman more than any other SP really. It's just that everyone is asking $50 for their beater. Is it the last card people need to finish because it's the rarest, or because a card of a common player goes for a pretty penny that people don't really want to pay until it's the only thing in the way of completion?

The cards considered scarce fluctuate with time. I recall when Perry and McCovey were considered awfully tough, and today they aren't. My 2015 Standard Catalog doesn't even list Snyder as a SP at all, but I recall when he was considered one of the toughest SP's and was frequently one of the last ones folks needed. From my own experiences, the SP's seem to all exist in roughly equal population over time, though some can seem tougher over a certain stretch. There have been good threads on Net54 before on these, but I've never seen any uncut material that might help show whether Coleman, Jackson and others are actually tougher, or if people just think so.
