There are no spectacularly rare cents from the 1960s because huge numbers were minted every year.
The only date that's even slightly valuable is a 1960 small-date cent, which has a small circular zero in the date rather than a larger oval digit. But even so, these sell for less than a dollar in circulated condition.
If you mean a penny from 1960 the answer would be one penny. These coins are not rare and can easily be found be searching through pocket change. If you mean pennies from the 1960s the answer would still be the same. Again these can easily be found in pocket change.
A rare date for wheat pennies would be 1909 S VDB.
