David if I could, remove the coins from the set and place them in mylar holders or a coin cabinet, the set has an air leak obviously which is leaching air into it.
I am considering a 1984 set with the same issue, halos of tarnishing on the Cupronickel but the Bronze and brass are fine - although in your case they are not.
When you remove them, use gloves or handle by edges with clean hands and fingers - like coinfrog said, do not try to clean or dip them in any way.
Value wise, the dealers I work with say they have high cat values of like £35 or £40, but demand is quite low, as mintage numbers were high (100k+) and there is no precious metal content in these sets. A good set is worth to me around $25 NZD and an impaired one like yours - half that figure.
To be honest, you could probably get a fault free one quite cheaply like AUD $20 from a dealer desparate to offload it.
Don't worry I have a thing for BU and Proof English modern coins too - I just spent about $60 on the 1983 - 1986 UNC sets.

Lots of GB proof sets from this period are in similar condition. If you wanted to sell the coins, you might do better by breaking up the set and offloading the 2p. 5p and 10p separately - these were not issued for circulation, so there is always a market for them with collectors wishing to put together date runs.
