Unless they have been reviewed before, I would recommend taking the time anf effort to review them, as there are many pennies with high values, such as the 1955 dbl die or 1969 small date. Indeed, these are rare, and most likely there will not be any of note in your collection. What I have done when reviewing dozens, if not 100s, of coins, is to familiarize myself with the high rarity rating varieties and low mint numbers and then see if any of the coins meet those criteria.
Sort of a schrodinger's cat of coins.
I will give an example; Someone was selling an 1880 seated liberty dime, but did not realize that it was a low mint date. I profited several 100 dollars on the resell.
The recommendation of asking a competent (and trusted) coin dealer or collector is a good idea.
