Spawn #9 was heavily printed, but it's 20ish years old, lots of lost, destroyed copies. Also, Angela is going to be joining the Guardians of the Galaxy team in issue #5, co-written by Neil Gaiman, his return to comics. Could cause Spawn #9 to go even higher. If you can find a NM copy for $10 or under, pick it up IMHO.
