George V gold Proof Sovereign 1923-SA PR64+ PGCS, Pretoria mint, KM21. Beaming with harvest-gold luster, this flashy example displays virtually as-struck devices atop deeply-mirrored fields that contain a few unremarkable wisps which are noted in the grade. A scarce type with a mintage of just 655 proofs, and a coin that is decidedly nicer than those typically encountered.
Estimate: 3000-3500 USD
