Good one on the F76, grab these best known examples of rarities if money allows, otherwise you may regret it ever after.
I still occasionally rue the day my computer cocked up as I was about to bid for I think the finest F7 with virtually full orange glow (not streaky as often seen) at the Spink Dec 2015 sale. At the time I thought I'd never see another one like that and of course I haven't since. It went for £1100 hammer which was written up in Coin News as a high price, but I think it was a snip for whoever got it.
