As of my last knowledge update in January 2022, the 1933 Double Eagle is indeed a highly valuable and historically significant coin, but the reported value of $18.9 million+ is particularly noteworthy.
The 1933 Double Eagle holds a special place in numismatic history due to its unique background and rarity.
Recall and Melting: The U.S. Mint was ordered to melt down the 1933 Double Eagles, and most of them were destroyed.
Legal Disputes: Due to the controversy surrounding their ownership and the legality of their possession, the 1933 Double Eagles became the subject of legal battles. In the 2000s, the U.S. government and a private collector reached an agreement to allow the sale of one specimen at auction.
Auction Records: The reported value of $18.9 million+ may be associated with the sale of the 1933 Double Eagle in a public auction.
Condition and Provenance: As with any rare coin, the condition of the 1933 Double Eagle and its provenance (ownership history) play crucial roles in determining its value. Well-preserved specimens with a documented and prestigious ownership history often command higher prices.
While the $18.9 million+ valuation is in line with the extraordinary value associated with the 1933 Double Eagle, it's important to verify the information with current sources
