Great Britain
Victoria Gothic Crown 1847, S-3883, ESC-291 (rare), L&S-58, KM744, plain edge, PR65 PCGS, splendid rich blue iridescent toning with hues of golden amber, the mirrored fields beneath the color intact. Plain-edge proofs are far rarer than lettered edge pieces and probably are actually patterns. The last one we had, in April 2012, sold for $16,000 in the same grade but from NGC.
Estimate: 12000-15000 USD
