Hello...my name is XXXXX XXXXX I can assist you, if you wish...I am very familiar with the ammunition, which is Nazi German manufactured and 9mm parabellum ("for war", or military grade) in nature, meaning it was designed for use in the P-08 and P-38 automatic pistols and a wide array of German and Italian 9mm submachine guns.
The cases are steel, generally, with mercuric primers and black laquer sealed bullets--German ammunition was of a higher powder grain content than modern 9mm ammunition for pistols, but it will fire just fine in any modern handgun.
The ammunition was originally designed to fit the "Luger" P08 pistols, and the typical retail on the collector market is from 75 cents to $1 a round with that headstamp and date.
A full box, as you have, with paper label, would enjoy a premium with collectors of an additional $15-20 over the actual value per round, or from $27 to $36 per box in most regions. Most are advertised in the $40 to $50 range, like this example:
And here is another example:
You can legally sell it on a site such as Gunbroker.com or Auctionarms.com as long as the buyer is at least 18 years of age. If shipping, you must, by law, mark the box "ORM-D" and require a signature.
Please let me know if I may assist you further...I will give one of my requested questions to Glenda as this was intended for her, but I know quite a bit about the ammunition, being retired from the US military.
With kind regards,
