Not every silver coin qualifies for a self-directed IRA. The Internal Revenue Code — specifically IRC §408(m)(3) — sets the legal standard: a silver coin or bullion must have a fineness of at least .999 (99.9% pure) to be held inside a tax-advantaged retirement account. There is one statutory exception: the American Silver Eagle, which is .999 fine but is explicitly named in the Code regardless of fineness, giving it an unconditional green light.
Beyond purity, the IRS requires that eligible silver come from a national government mint (such as the U.S. Mint, Royal Canadian Mint, or Perth Mint) or from an LBMA, COMEX, or NYMEX approved refiner or assayer. Privately minted rounds and bars must carry a hallmark from an approved refiner and meet the .999 threshold to qualify.
Two disqualifiers trip up many investors. First, junk silver — pre-1965 U.S. dimes, quarters, and half-dollars — is only .900 fine (90% silver) and therefore prohibited inside an IRA. Second, numismatic and collectible coins — including certified, graded (PCGS/NGC), or rare-date coins valued primarily for their collector premium rather than their metal content — are explicitly excluded under IRC §408(m)(3)(A). Their collector value is irrelevant; what matters is whether the IRS classifies the coin as a collectible, and numismatic coins always fail that test.
In practice, stick to sovereign mint coins with .999+ stated fineness and you will be safe. The section below lists every major eligible coin.
