Private mints also produce 100 ounce silver bars; these are a little larger in size than an ordinary building brick.

They offer a convenient way to purchase precious metal and are readily tradable throughout the USA and in most areas of the world.

These pieces, if from a "Premium" mint that maintains an ISO9000 standard are eligible for placement in an IRA.

It is best, however, to verify which bars are eligible with your personal plan.
