Know the difference between handmade (individually crafted), machine-made (ceramic or glass manufactured on a machine) and contemporary (modern marbles made by glass artists). Old, handmade marble generally have a pontil, a rough spot where the sphere was removed from the glass cane. Be familiar with leading marble manufacturers such as Marble King and the Akron Agate Co.

According to AkronMarbles.com, onionskins, a handmade marble with elongated colored flakes over their surface, are a significant find.
