Autoharp-style chorded zither bearing Chromaharp markings

This musical instrument appears to be a 15-chord autoharp-style zither, displayed within a black hard-shell carrying case with yellow stitching. The body features a glossy sunburst finish, transitioning from a dark perimeter to a bright yellow-orange center. It bears a visible red and gold decal reading 'Chromaharp' by 'Rhythm Band Inc.', which is consistent with mass-produced instruments from the mid-to-late 20th century. The instrument is equipped with a mechanical chord bar assembly containing white plastic buttons labeled with various chords, including 'C Maj', 'G7', and 'Am'. The metal tuning pins are visible at the bottom and along the left side, some accompanied by white circular lettered labels for note identification. A small yellow label at the top indicates it was 'MADE IN KOREA'. While the markings suggest a specific brand, this is treated as a hypothesis subject to physical inspection. Visible condition includes surface dust, minor scuffs on the chord bar housing, and some fraying to the interior lining of the case. The presence of all strings cannot be verified from the image alone, and the functional status of the chord dampening mechanism is unverified.

I have examined the images of this 15-chord zither-style instrument. Based on what I can see, the item bears markings consistent with the 'Chromaharp' brand by Rhythm Band Inc. and includes a 'Made in Korea' label, which suggests a mass-produced model likely from the late 20th century. The sunburst finish and hard-shell case appear to be in fair to good cosmetic condition, though I cannot verify from a photo the functional integrity of the chord bars, the presence of all strings, or the stability of the soundboard under tension. The value estimate is based on the hypothesis that this is a functional Chromaharp; however, this attribution should be treated as a working assumption as markings can be replicated. Modern mass-market autoharps of this type typically occupy a stable niche in the secondary musical instrument market for students and folk enthusiasts. The presence of the original case adds a modest premium. To provide a more precise valuation, a physical inspection is required to check for structural cracks, tuning pin torque, and feltpad wear. Provenance documentation or original purchase receipts would also aid in establishing its history. If this were determined to be an unbranded 'in the style of' instrument or a less-regarded reproduction with inferior internal bracing, the value would likely decrease to a range of $40 - $70. The current estimate assumes the attribution is correct and that the instrument is in playable condition.
