The Maryland General Assembly has passed Senate Bill 309 (SB 309), landmark legislation that expands the state's sales- and use-tax exemption for precious-metal bullion and coins, marking a significant development for the numismatic and bullion community.
A wide range of U.S. and pioneer gold coins from 1798 to 1933 proved to be highlights of the February 3 Stack's Bowers sale of the second part of the James A. Stack Sr. Collection.
Under the provisions of the Circulating Collectible Coin Redesign Act of 2020 (Public Law 116-330), the U.S. Mint will be offering new designs on the half dollar in a four-year program from 2027–2030.
