Great Britain
George II Proof Crown 1746 PR65 NGC, KM585.2, S-3690. A beautiful example of this proof-only issue, and tied with five others for the finest graded at NGC. A very well-struck issue, this coin has mostly gray toning with subtle flashes of blue and purple that appear when held in the right light. For the grade-conscious collector of British crowns, it doesn't get much better than this!
