What Does The U.S. Mint Do With Coins That Are Unsold?

By GovMint :

When coins produced by the U.S. Mint remain unsold, the Mint has a few options for handling them. In some cases, unsold coins may be melted down and recycled to recover the metal content, especially for bullion coins made from pure silver or gold. This process is known as “de-trashing” and involves many steps. The Mint may also hold onto unsold coins as part of its inventory for future releases or special promotions. Usually, these coins are offered to select bulk dealers, sometimes in sealed-bid auctions.
