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.
