IRA-Eligible Gold
IRS rules generally treat metals and coins as collectibles, with exceptions for specified coins and qualifying bullion.
Do not assume every gold coin qualifies
Publication 590-B specifically identifies U.S. gold coins in certain denominations and certain qualifying bullion as exceptions. Dealer product lists can be useful, but the custodian/trustee should confirm eligibility before the IRA buys an item.
Custody still matters
Qualifying bullion must meet the applicable physical-possession rule. Personal home storage can create serious tax questions.
