Exempts sales of investment metal bullion and certain investment coins from sales and use tax.

This bill exempts sales of refined precious metal bullion (like gold, silver, platinum, and palladium bars) and high-value numismatic coins ($1,000 or more) from New Jersey's sales and use tax. It directly affects buyers purchasing these specific investment-grade items, not jewelry or art made from them. The law defines "investment bullion" as unprocessed metals where value depends on metal content, excluding fabricated items like jewelry. It also excludes commemorative medallions and coins used in artistic works from the exemption.
