What is the value of a 1958 US cent?
Unless it is special in some way, i.e., uncirculated or proof ,
it is worth one cent. A nice uncirculated one might retail for
25-35 cents, while a proof might be 35-50 cents.
1958 is the last year for Lincoln cents with the wheat ears on the back -- and they made a lot of them. If yours is anything less than an absolutely perfect flawless mint red gem, its value will be only a couple cents. FYI, most modern US coins, and many dating back to the 1800's, have E Pluribus Unum on them.
