EDISON DIAMOND DISC RECORD #80468 w. less common "label" c. 1915-19

Description

I believe this to be the intermediate "label" style, used after the earlier one (with copyright and Edison's image inside shields) and the later two which had paper labels.  If the number references are actually sequential, I'm thinking that 80268 would fall after 1915 but before paper labels in 1921.  It does not say "Thomas A. Edison, Inc." as on the early discs, but "The Edison Laboratories" like the paper labels. This one you see less often and if I recall correctly, they only did this version for one year, probably 1919 just prior to the transition to paper.  Just can't remember the actual year!
It just so happens, I noticed that #80267 sold on eBay very recently, so if you're collecting them sequentially and you're that buyer...  Well, here you go!  Apparently, there were 26,000 titles available, divide by half for two sides, and the newest discs would be around 12,000.  That's my thinking, anyway!
I have three.  They were my grandparents' records.  The other two are older yet. There were tons more, but they switched to an RCA Victrola sometime in the 1920s and gave most of them away eons and eons ago.  (I know this because I have that "radio" cabinet and the records and the leather cases, but not the actual victrola.  All the hardware, but it was replaced with a regular turntable in the 1950s.  Which is immaterial!  But, vaguely interesting.)
The photos reveal chips on this one along the edge.  A hefty one in one spot and some negligible chips on the other side.
