It will be close to impossible to find them in circulation. 58' dimes and quarters are silver so they'll most likely already be picked out. Then there are 58' wheat cents which are rarely found in change today. Also 1958 was almost 60 years ago and every year after that billions of coins of each denomination were minted every year, making the chance even more slim.
I do agree with mark and highly recommend buying the coins separate or in a mint or proof set.
