While reviewing the initial results in various categories of recent auctions, my initial take is that the sales were moderate to strong.
2025 $25 Palladium Eagle, Proof (2018–) Values
Greysheet & Red Book® PRICE GUIDE
The Greysheet Catalog (GSID) of the $25 Palladium Eagle, Proof (2018–) series of American Eagles in the U.S. Coins contains 1 distinct entries with CPG® values between $1,993.06 and $2,268.06.
Proof $100 platinum American Eagles have been made each year since 1997 and are the last of the platinum bullion coins to be made by the United States Mint on an annual basis. While many of the $100 proof platinum eagles trade for prices well above spot values, this fact does not seem to faze collectors, who enjoy purchasing these hefty -- and pricey -- numismatic marvels.Proof $100 platinum eagles are generally low-mintage coins, with several proof issues carrying mintages as low as 5,000 pieces. For the first decade or so after the series started collectors ignored the rarity and value presented by the low mintages. That changed and the scarce proof platinum eagles are seeing increasing demand.
