The United States Mint said on Tuesday it was unable to meet surging demand for its gold and silver bullion coins in 2020 and through January, due partly to pandemic-driven demand and plant capacity issues.

For this year, the U.S. Mint has a limited window to produce its current gold and silver coins, with redesigned coins expected to debut in the summer. It is limiting distribution of its gold, silver and platinum coins to specific dealers because of heavy demand, and a limited number of suppliers of metals, it said in a statement.
