The value of a baseball signed by Richie Ashburn, Del Ennis, and Robin Roberts in poor condition typically ranges from $50 to $150, depending on the extent of the wear and the market demand at the time of sale. Factors such as authenticity, the ball's overall appearance, and any additional provenance can also influence its value. Collectors often prioritize condition, so a ball in poor condition may be less desirable.
