Is a Scrapped T206 Broad Leaf 460 Sheet Being Broken Up Slowly?

About 18 months ago, the Snodgrass above was sold via Hunt Auctions (I can’t remember the exact date, and there doesn’t seem to be any record of the sale online).  Two month ago, this Griffith appeared on eBay:

If you take a close look, you’ll see that both cards are hand-cut.  They have large, wavy, and uneven borders.  When I saw the Griffith it immediately reminded me of the Snodgrass.  At that point I wondered if there were others from the same sheet.  But, two copies wasn’t really enough to assume there was a larger pattern.

Eight weeks after Griffith was listed on eBay, the below Harry Davis appeared.  At that point I was convinced these three cards came from the same sheet.

The question was: “Are there any others?”  I didn’t have to wait long to find out.  REA’s Summer 2019 Auction went live this week and among the predictably staggering offerings were these hand-cut Broad Leaf 460s:

Now that we know these six cards very likely originated from the same sheet, a couple questions come to mind.  Are there more that will come to market soon?  And if there are, what effect will that have on prices for Broad Leaf 460s going forward?
