No. Gold IRA possession ends the account's tax shelter, because collecting the coins is an in-kind distribution taxed at market value on the day it ships, with a 10% penalty on top below age 59 and a half.
You can have the metal, but the moment you take it the holding stops being retirement property, and the custodian records an in-kind distribution at market value on the day it ships. That value becomes income for the year, and a 10% early-withdrawal penalty applies on top if you are under 59 and a half at the time.
After age 73, or 75 for anyone born in 1960 or later, required minimum distributions begin and metal creates a practical problem cash does not, because a coin cannot be divided to hit a number. Meeting the requirement means selling part of the holding or taking coins in kind and paying tax on their value, and both cost more than transferring cash would.
