Any idea when these were made and what they might be worth?

Might want to cross post this in the cartridge collectors forum.

I can not help with your question but will follow so I can learn.
Pinning down what era they are from will help with determining what, exactly, they were for.
AFAIK, the standard .45ACP was all that the government used, would be interesting to learn that these were for some testing protocol as a way to upgrade the standard GI pistols.
Thanks

I contacted a serious cartridge collector who didn't know the date (the cases are not marked) but he gave me a price of $50.

Actually libertytreecollectors has these in there collectable ammo section:

38 Super US WW2 Ammunition OSS - Ammo Collectable

Colt 1911's in caliber .38 Super were ordered by the Office of Strategic Services OSS. This is the original ammunition.

Only 3 manufacturer lots are known 5001, 5002 and 5003. These boxes are clearly marked on the front 5002. Cartridges are clean looking brass cases, FMJ projectile and a standard commercial head stamp in a military kraft colored box. These boxes came out of the sealed spam can from the original wooden crate.

I'll sell them for $55 + shipping.
