Exemption on precious metal bullion expansion to include coins and other forms of currency

This bill expands Minnesota's sales tax exemption for precious metal bullion to include coins and other forms of currency that serve as legal tender. It directly affects buyers and sellers of gold/silver coins (like commemorative or circulating coins) and other metal-based currency, making their sales tax-exempt under the same rules as bullion bars. The key change amends Minnesota Statutes 297A.67 to add "coins and currency" to the exemption, while explicitly excluding jewelry, art, and scrap metal. The policy change takes effect for transactions after June 30, 2025.
