The US Mint has just published November 19 as the official release date for the Dolley Madison First Spouse Gold Coin. This is four days later than the corresponding James Madison Presidential Dollar release on November 15.
The coin will be available in Proof or Uncirculated. The offering price has not yet been published. However, it seems likely that it will be above the price of the first three First Spouse coins since the price of gold has increased substantially. (The prices for the prior coins were $429.95 and $410.95 for Proof and Uncirculated, respectively.)
On the same date, the Mint will also be offering new Four Coin Presentation Cases to house the First Spouse Gold Coins. Separate cases for Uncirculated and Proof coins are listed.
