The value of a Columbia graphophone can range widely, depending on its age, condition, and rarity. Generally, a Columbia graphophone in good condition can be worth anywhere from $200 to $3000.
Graphophones made in the early 1900s, such as the Columbia Disc Gramophone, can fetch higher prices due to their historical significance. Rarer models, such as the Columbia Viva-tonal Graphophone, can also be worth more.
It is important to note that the value of any antique or collectible is subject to market conditions, and the actual price realized may vary.
