How to Avoid the Biggest Mistakes 254 Warning! Just in case you were thinking of it ... you can't use IRA assets to purchase things like art, antiques, stamps, or other collectibles. Investing Question #6:Can I put gold coins in my IRA? Answer:Yes and no. Your IRA plan may invest in certain gold and silver coins issued by the U.S. government and coins issued by an individual state. You are able to invest in bullion, gold, silver, platinum, or palladium coins for your IRA. But the bullion and coins must be in the possession of the IRA trustee, and most trustees will not want the job of guarding your precious metals. Another way to invest in gold is buying mining company stocks or mutual funds that invest in precious metals. Investing Question #7:How do I know what my company charges me for the administration of my 401(k)? Answer:By law (the Employee Retirement Income Security Act--ERISA), plan sponsors are re- quired to tell you what you are being charged for, how much you are being charged, and how those costs were determined. You may have to take a look at the plan document and make a few phone calls to the benefits department before you get an answer.
