I collect baseball memorabilia also.
Live near Youngstown Ohio so I spent lots of time in Forbes Field and Clevelands Municipal Stadium. Now the Jake and PNC Park.
60s' Pirates....great team. Maz is in the HOF...Clemente in right field with a shotgun for an arm.....no one...but no one would run on his arm. Remeber Dick Stuart? AKA as Dr Strangelove because he had an iron glove....couldn't field anywhere worth beans.
Law, Face...Bob Friend...Groat, Skinner, Virdon.....just to name a few.
Never....ever sell that ball....it makes Yankee Fans wince
