Description
The 1999-W $5 Unfinished Proof Dies Gold Eagle, an exceptional error coin from the U.S. Mint marked by the inadvertent use of proof dies for minting regular strike coins without the intended "W" mint mark, is certified by NGC. This mishap led to a limited production run, with estimates suggesting possibly around 6,000 coins minted if only one pair of dies was used, though the exact mintage is unconfirmed. The coins, due to their scarcity and the series' popularity, are considered modern collectibles with a strong potential for appreciation in value.
