Please wait for an official confirm from one of the certified authenticators on this thread, but insofar as pre-creed is an area in which I do have some expertise, I'll offer the following amateur assessment:
The listing appears to show an early version of the Dinky Shopping Bag Tote from the early-to-mid 1960s. I'm basing its age from an unofficial chronology of labeling practices I've hypothesized over the years where the white fabric "Cashin-Carry for COACH" tags were employed in the period prior to the introduction of the "Bonnie Cashin" black metal tags + red fabric "COACH Leatherware A BONNIE CASHIN DESIGN" tags, which in turn were replaced by the "COACH" black (or on rare occasions, pewter) metal tags (+ "COACH" cartouche hang tags found on all bags after 1970 or so), followed by the "COACH" cartouche imprint (or riveted leather "COACH" tags on those styles that couldn't easily accommodate the imprint), followed by the creed stamp (sans numbers), and so on). Again, this timeline is something that I've come up with and certainly could and should be up for debate. Also, I've intentionally left off assigning specific years since doing so without sales receipts to support them would be purely speculative on my part.
The bag shown in the photos compares well to the ones I have of this particular raw-edged rendition of the Dinky Shopping Bag Tote with contrasting thread with the exception of the fabric on the interior bottom panel. In all of mine, which for transparency I'll disclose are actually later (mid 1960s) versions identified with the BC metal tag + red fabric tag and have an interior canvas fabric pocket secured by a leather flap and turnlock that were added to the style) the fabric is the earlier signature "Mexican" stripe (without the black separating thread introduced later). And though BC did employ plaid fabrics, as well as alternate stripe patterns in the earliest bags, in all my years of looking I've never run into a black-and-white checkered pattern before. I will though applaud whoever restored the edge-paint to the raw side and handle tab edges. Having to do so is typical, time consuming, and a challenge to do well.
If I could be excused for doing so, I'd offer the following suggestions/theories about the bottom panel:
I've some Cashin-Carry for COACH shopping bags from the same white-fabric tag era as the one shown in the listing, albeit the ones I have are of different sizes: the Shopping Bag Tote (same footprint as the Dinky, but taller), and the Large Shopping Bag Tote (which is the same height and a few inches wider than the aforementioned size and has finished edges on the sides). Neither of these larger styles show any evidence of ever having fabric-faced bottom stiffeners, but instead have rectangular leather pieces that have bonded to the inside bottom and cover the bent over tabs from the four metal feet. I'll volunteer that these bags would certainly have benefited from having a bottom stiffener since they tend to be floppy without one. In fact, I've made removable ones (using hobby board and some Mexican stripe fabric I happen to have had on hand) to help them hold their shape. Perhaps a previous owner of the bag in the listing came to a similar conclusion, but did not have any fabric similar to the varieties used by BC during that period.
My second suspicion is that perhaps somewhere along the way the original fabric-faced cardboard panel that was adhesively attached to the bottom (if indeed like in the versions I have, there was one) has been replaced. These panels do have a propensity for coming loose over time. I'll also share with you that over the years I've had to replace several bottom panels on bags where a prior owner bathed the bag, not realizing that there was a cardboard element whose integrity would be compromised by getting soaked as well as waters detrimental effect on the adhesive(s) used to bond the fabric to the cardboard and the cardboard to the leather. As for where the original fabric may have gone, I'll only add that I've seen more than a handful of bags from this period come to market missing the fabric from the cardboard stiffeners, which is why I continue to keep an eye out for totally trashed bags from this era so that I can perhaps salvage the fabric (and other components) for future repair efforts.
I'd say that was at least three cents worth. I trust that no one will be offended by my attempt to provide input.
