Goofball is the name given to these simple swirl marbles. Most of my Goofballs will have a black base but a few have other color base glass. All Goofballs are opaque glass. A few are coated with clear glass, most are not.
Goofball does not relate to any mistakes...they are named for goofy fun!
Goofballs range in size from peewee to 1-3/4 inch. Price ranges from $6 for peewees, $15 for 5/8 inch, and from $20 up to $95 for larger marbles. Most larger goofballs range in price from $40 to $75, the most common size range is about an inch to 1-1/4 inch.
