Just found this Mason jar in a box in my garage! Has zinc lid, side seams and glass bubbles. 1.5 qt. size. Is it unique?

No, it isn't really unique.

After it was discovered that Mason's patent had expired, many other manufacturers produced glass jars for home canning using the Mason-style jar.[8] "Patent Nov 30th 1858," signifying the date of Mason's patent, was embossed on thousands of jars, which were made in many shapes, sizes, and colors well into the 1900s. Since they were made in such quantity and used for such long periods, many of them have survived to the present day.

" This “MASON’S / PATENT / NOV 30TH / 1858” phrase was originally embossed on countless glass fruit jars (canning jars) ranging in age from circa 1858 to the early 1920s."
