Watch List notes:

Brazil (Rio mint), gold moeda (4000 reis), Joao Prince Regent, 1812 with date as 181.2 (rare), NGC MS 65. Gomes-33.12; Russo-572a; KM-235.2. A gorgeous coin with deep red toning over strong luster throughout, in fact tied with five others for second finest in NGC census behind a single MS 66, but unfortunately it is unknown whether any of those are the same 181.2 error as this coin (presumably none), of which we could find no other examples sold in recent years. NGC #4883508-002.

Estimate: $1750-2500
