I have a small collection of steel pennies I got from the American Historic Society and noticed that some of them have the Denver mark, some have the San Fransisco mark, but the (I assume) Philadelphia-struck pennies have no mint mark on them. Anyone know why? I've already verified their authenticity with a magnet (since steel pennies are the only US coins that are attracted to magnets) so I know it ain't fake.
