Bern. Canton gold 2 Duplone 1794 MS63 NGC, KM147, Fr-186. Highly unusual quality for the issue with full prooflike reflectivity in the fields, sharp detailing throughout the design and no marks that demand individual attention. The finest we have seen after a scan of archived auction sales and the single highest certified example seen by NGC.
Estimate: 3000-4000 USD
