Vitaphone Disc Values

[rodpickett]

Does anyone have knowledge about the current value range of Vitaphone Sound Track Discs? Following is a brief description from Wikipedia:

In 1924–1925, when Western Electric established the format of the system which would eventually be named Vitaphone, they settled on a 16 inch (40 cm) diameter disc rotating at 33 ⅓ rpm as a good practical compromise of disc size and speed. The slow speed permitted the 11 minute playing time needed to match the maximum running time of a standard reel of film projected at 24 fps, yet the increased diameter preserved the average effective groove velocity, and therefore the sound quality, of a smaller, shorter-playing record rotating at the then-standard speed of about 78 rpm.
