Pedro II gold 10000 Reis 1839, KM451, Russo-620, AU58 NGC. Mintage: 567. Impressively struck and reflective in the fields with orange and reddish tone encircling the peripheries that adds to the character. Highpoint friction is barely noticeable. A low-mintage date and the key to this "child head" type with the only other example we were able to trace appearing in a group lot within the incredible Norweb collection.
Estimate: 5000-7000 USD
