Actually, the San Francisco Mint is still striking all denominations from 1¢ to $1, but only for proof sets. All carry the S mint mark.
Circulation cents with an S mint mark were struck there from 1909 to 1955, and from 1968 to 1974.
There have been occasional small runs of other dates at both San Francisco and West Point when demand is high and the Mints at Denver and Philadelphia are maxed out, but these coins don't carry a mint mark and are indistinguishable from Philadelphia strikes.
There was a brief period of 1965-67 when no U.S. coins had any mint marks. However, since 1968, D and S mint marks returned, and P was added to most coins in 1980. Philadelphia pennies still lack a mint mark, but Denver ones are marked with D, and proofs from San Francisco have the S.

The last year for wheat pennies was 1958.
Due to the rising price of copper, pennies were worth more than face value.
Solid copper pennies were last minted in 1857 and were much larger than today's penny. Pennies were made mostly of copper until mid-1982, when the composition was changed to 97.5% zinc with a plating of 2.5% copper. The only exception was in 1943 when wartime copper shortages forced the Mint to make pennies out of scrap steel. Bronze cents were resumed the next year, 1944.
Because it costs more than a penny to produce a penny.
they still make pennies

Not really, as there are billions of them already in circulation.

Not any time soon. There are billions of them in circulation.
1943-45
Probably because of their impending involvement in WWII. They will have needed it '...for the war effort...'
