Unfortunately I can't give you an answer to this as we don't share Supply Cache statistics..
Sorry!
Edit: The Patch Notes do mention however that the more valuable the item, the rarer it will be.
This still does not say if they are weighted on the roulette wheel or not, this could mean that more valuable items have a slimmer chance of actually appearing in the chest correct?
In that case if you get a worthless crate, sell it back its right here at the bottom.
For some of the higher-value items you can acquire from a Supply Cache, such as a Summoner SMN-D (including a Mech Bay to house it) or a 1000 MC pack, the value of a Supply Cache Reward can far exceed the value of the Supply Cache Key used to unlock it. The more valuable the item however, the rarer it will be!
In addition to high-value items Supply Caches will contain items on the lower end of the currency value spectrum, such as an SRM 4 or a Targeting Computer MkIV. If you have no use for those items as equipment you can choose to sell them back for C-Bills through your Inventory screen.
In the case of the SRM 4 and TC, both with a standard purchase cost of 120,000 C-Bills each, their re-sale values would be 60,000 C-Bills. With a Supply Cache Key cost of 25 MC this translates to approximately 2,400 C-Bills received per MC spent; better than the 1,375 C-Bills-per-MC value you would receive from acquiring a 1,100,000 C-Bill Pack for 800 MC!
