There is no good reason to not open it as it is just a regular roll of quarters at this point. Errors can occur randomly in any year and most good errors won't even fit in a roll. As for varieties, there are a few minor doubled dies and one RPM(1989-D).
I did find reference to the "error" your dad might have been referring to. In 1989, some quarters were discovered without a mintmark. A frenzy ensued and interest soared with huge prices being attached to these quarters. Then the Mint debunked the error, attributing the missing mintmark to a clogged die, and that oddity faded back into obscurity.
With any luck, that roll will have some nice BU 1982P&D, 1983P&D, or 1986P&D quarters. All of them have seen nice gains in value and nice ones can be tough to find.
