Since that night, the dollar has lost over 85% of its purchasing power - and retirement savers have absorbed the cost. U.S. Code Title 31, Section 5117 gives the Treasury authority to reprice America's gold reserves from $42 per ounce to today's market value - a gap of 107x. More than 60 million Americans can move into physical gold inside a retirement account, tax-free and penalty-free.Download the free 2026 Gold Guide to see how it works10/17/2025Gilbert Ray Cisneros, Jr.House (D-CA)Buy$936.33$1,001 - $15,00010/17/2025Shelley Moore CapitoSenate (R-WV)Sell$936.33$1,001 - $15,00010/9/2025John BoozmanSenate (R-AR)Buy$942.89$1,001 - $15,00010/7/2025Ro KhannaHouse (D-CA)Sell$914.80$15,001 - $50,0009/29/2025Russell D MillerEVPSell3,381$915.00$3,093,615.00 9/29/2025Ro KhannaHouse (D-CA)Sell$916.87$1,001 - $15,0009/23/2025Val T.
