The cheapest Ed.VIII is probably the halfpenny reverse uniface. It's currently in a 65(?) slab and last sold for around £3000-3500. You might find another pattern uniface for less than 10K, but after that you are talking £20K and up. I started with my budget at £200 per coin. I already paid two or three times that in some cases. I didnt know all EVIII are fantasy pieces. In this case i might leave a gap.I never liked him anyway.
