Possible cut t206 sheet from ebay... Opinions?

[t206fix]

Recently Greg Morris auctions sold a group of Sweet Cap factory 25s on ebay that I believe were part of an original sheet (or sheets). The back cuts are alcl the same, which may be too big of a coincidence coming from the same collection. Also, all of the cards are marked with either a HD back stamp, or a cursive HD. I've reached out to GM on ebay, but they had no idea of where the collection came from (I was hoping for more info from them). Here is a link to one of the auctions, and you can use "sold items" to view the rest of the auctions:

I'll also apologize in advance for the multiple posts. I can't seem to figure out how to post pics in between words .

A few observations from that auction:

1. There were a significant number of tougher Sweet Cap 350 factory 25s. I've been following all 25s for awhile, and there were multiple cards in that auction that I only see pop up in auction every few years. However, in this auciton, there were multiple single copies.

2. The Bender 350.25 has a visible pencil mark (possible indicating hand cut). I do believe other cards have pencil marks as well, but it's hard to tell from the scans.

3. The Meyers has a paper fragment, as if it was cut recently. This may be a large jump, but I thought it odd that a card cut 110+ years ago has this dangler (I know that it may be something else, so this is a wildly speculative).
