Your question is somewhat vague. Are you talking in general terms about the earliest 9 mm Parabellum cartridges from various countries, or do you mean the earliest known single specimen of the 9 x 19 mm cartridge, which is German?
If the latter, it is a scarce round. It has a brass case and primer, and a CNCS truncated FMJ bullet. The headstamp is * D.M. * K. This is presumed to be the earliest serial production cartridge. There may have been earlier ones. The cartridge called for years “9 mm Borchardt” is actually part of the development of the Luger pistol, not the Borchardt, it would seem, and possible predates the 9 mm Luger case type as we know it today.
Regarding a full box, in 45 years of collecting this cartridge, I have never had my own eyes on the box for this ammunition. There was an early DWM box pictured in the fine article on “The Genesis of the 9 mm Parabellum Cartridge,” by Dr. G. L. Sturgess, IAA Journal 444, Jul/Aug 2005, pages 4 - 15. The style of the box was likely similar to that shown in Dr. Sturgiss’ article.
The first serial production probably dates from 1902. It is not absolutely known if the rounds bearing the D.M.K. headstamp are actually the first of the serially produced cartridges, or if they were part of a prototype “trials” lot. They are, regardless, very hard to find even in a single specimen.
Early German rounds are not extremely rare, although as the years pass, they become, of course, less and less encountered. They have the headstamp K DWM K 480C, and the headstamp letters of the early rounds are with serifs (old-style letters). They will have brass primer cups and the earliest will have CNCS FMJ truncated bullets, or the hollow-point version of the same.
