Great Britain
Victoria gold £5 1887, S-3864, KM769, Jubilee Head, AU58 NGC, a coin that once must have resembled a proof, for its surfaces are deeply mirrored and the strike is really bold, but a large number of small abrasions have marred both sides. A banker's piece? Still, lots of value here, intrinsic and otherwise.
