Just got this as an email from the Mint:
Order Update
Dear ,
Thank you for your Morgan Dollar purchase supporting this historic program’s centennial anniversary. We are grateful for your support and are excited to offer the Morgan and Peace Dollars program.
Due to a system error, you may have seen an estimated ship date of June 2021 when completing your purchase. As stated on our webpages and in the prelaunch emails, these coins will be shipped in October or November. While we regret the delay, this special coin is sure to be a standout addition to your collection.
We appreciate your interest in the Mint's numismatic programs.
