Before I do anything stupid ... Collectable ammunition

[Dark Skies]

My club had a clear out of old .303 ammunition. I scooped the lot, intending to break them up and recycle the bullets for reloading.
The bulk are plain old RG .303 Mk7 of late fifties vintage.

However, I have three original boxes of ammunition that might be collectable and want to pick your collective brains lest I ruin something of historic value.
First up, a box of twenty rounds marked WRA 1941 .303 with the primers crimped in place with four staked stampings.
Are these rare / collectable / interesting enough not to be broken down?

A Box of 32 cartridges in what appears to be the original box. Seal around box reads .303 Inch Mk7 Broad Arrow I.S.A.A
Ammunition within stamped U ◇ 1943 VII v The bullet crimp isn't the usual full circumference, instead, it's a set of four rectangular crimps spaced around the cannelure

And finally. A tatty box of 48 rounds in a box simply marked 48 Cartridges with a broad arrow within a circle and C.I.A. stamped underneath.
Ammunition within is in good shaped. Marked DAC 1943 VII. Again only has the bullet crimped in place by four broken rectangular stampings around the cannelure.

They are all quite common, I bought a few of the wartime WRA red label RAF boxes (full) at a tenner each at the last Kempton show - same as in your first photos.
