This is the last bag of around 1,500 2004 JABO Fall Classics my late father bought at the JABO factory in 2004. 

The 2004 Fall Classics are known for their milky cream color, the deep, milky grays and blues and fiery reds and oranges that pop under UV. 

These are mint. They're mostly 5/8", with the exception of two cute little almost-peewee sized marbles and a larger, out-of-round, cream/blue/gray/yellow marble.
