Age and Rarity: The older the music roll, the more valuable it tends to be. Rolls from the late 1800s and early 1900s are considered more desirable and can fetch higher prices. Similarly, rolls that are hard to find or rare can also be more valuable.
Condition: The condition of the music roll is crucial. Rolls that are well-preserved, free from tears, rips, or excessive wear and tear, will be more valuable. Rolls that are still in their original packaging or boxes may also command higher prices.
Type of Music: The type of music recorded on the roll can also affect its value. Rolls featuring popular songs, classical pieces, or music by renowned composers tend to be more sought-after and can be worth more.
Manufacturer: Some music roll manufacturers were known for producing high-quality rolls, and their rolls may be more valuable. For example, rolls manufactured by the Aeolian Company, Welte-Mignon, or Ampico are often regarded as being of higher quality and can fetch higher prices.
Completeness: A complete music roll, with all the perforations intact, will be more valuable than one that is missing sections or has damaged perforations.
Historical Significance: Music rolls associated with famous pianists, composers, or historical events can also be more valuable. Rolls that were used in public performances, or that contain unique or unusual arrangements, may be of particular interest to collectors.
It's worth noting that the value of music rolls can vary widely, and it's best to consult with experts, collectors, or those experienced in the field of music rolls to get an accurate assessment of the value of a particular roll.
