Portugal 1800 10 reis
This specimen was lot 40012 in Stack's Bowers Summer 2026 Global Showcase Auction (Pittsburgh, August 2026), where it sold for $1,098. The catalog description[1] noted, "PORTUGAL. Mint Error -- Double Struck -- 10 Reis, 1800. Lisbon Mint. Joao as Prince Regent. PCGS MS-62 Brown. Already an intriguing coin on account of its advanced state of preservation, this SCARCE stunner is made all the more desirable due to its bold multiple striking." Numista states this issue was originally intended for the Azores but was later legalized for Portugal proper. The ten réis of 1799 was quite a bit heavier. João's mother, queen regnant Maria, began showing signs of insanity on the death of her husband and uncle Pedro in 1786. João became heir to the throne on the death of his brother José in 1788. When Maria was declared incurably insane in 1792, João reluctantly took over the government, not taking the formal title of Prince Regent until 1799.
