1911 was in the 20th century.

Assuming it's circulated and has no mintmark, the 1911 US Barber dime is a common coin. A coin in average condition is $3.00-$5.00.

All 1911 U.S. cents were made of bronze.

The only steel cents ever issued were dated 1943, and were made of that metal to save copper for the war effort.

If your 1911 cent appears to be steel it's almost certainly plated, not really steel. Try picking it up with a magnet. If it doesn't stick, it's not steel.

Sorry, no E series US coin of any type. But a 1911 Quarter Eagle has retail values of $178.00-$300.00 depending on grade.

The 1911 Liberty Head Nickel is the highest mintage year for the series and most coins show heavy wear and have values of $1.00-$3.00 better grade can be has high as $30.00 for circulated coins.
