LoveToKnow says that some old dishes have identification markings on the reverse side. This gives owners a head start in determining the value of the dish. Often times, the reverse side of the dish clearly marks the manufacturer's name. Others might have identifying marks that older manufacturers previously used when marking dishes. Sometimes the name of the pattern used on the dish is also on the reverse side. If the pattern name is not on the back, companies such as Replacements Ltd. offer a completely free database of images to help determine the style of the pattern.
