Folding pocket knife with markings consistent with Case XX Tested Centennial

This item appears to be a folding pocket knife, specifically a multi-blade trapper or folding hunter style, featuring a jigged red handle (likely bone or a synthetic composite) and polished metal bolsters. The long spey blade is prominently etched with the text "CASE XX TESTED CENTENNIAL" above the dates "1889-1989". A tang stamp visible on the smaller blade also bears a mark reading "CASE XX 1889-1989". A recessed oval shield on the handle scale contains the word "CASE". The handle scales are secured with three visible brass pins. The metal components show high-polish finishes with minimal visible wear, suggesting the item may have been a commemorative or collector's piece. While the markings are stylistically consistent with the W.R. Case & Sons Cutlery Company's 100th-anniversary editions produced around 1989, these markings are treated as unverified evidence without physical inspection, as logos and etchings can be replicated. The item shows no significant structural damage, though light surface scuffing is possible on the polished bolsters. The craftsmanship is consistent with late 20th-century mass-manufactured traditional pocket knives.

I have examined the images of this multi-blade folding pocket knife. Based on what I can see, the piece bears markings and etchings consistent with the Case XX Centennial series produced circa 1989. The spear blade is etched with the centennial dates (1889-1989), and the handle features a red jigged material with a 'CASE' shield. From a visual perspective, the craftsmanship and high-polish finish appear typical of collector-grade knives from that era. However, I cannot verify the material composition or structural integrity from a photo alone; a physical inspection is necessary to check for blade play, spring tension, and to confirm if the scales are genuine bone or a synthetic. The value estimate is predicated on the hypothesis that this is an official W.R. Case & Sons commemorative edition. These items are generally sought after by traditional knife collectors, though the market for 20th-century mass-manufactured commemoratives is stable rather than rapidly appreciating. If this item were to be revealed as a modern reproduction or if the markings were applied post-manufacturing, the value would likely drop to $20 - $40 as a utility tool. To confirm the item's status, a hands-on examination by a cutlery expert is required to verify the tang stamps and manufacturing techniques against known historical specifications. The presence of any original packaging or certificates of authenticity would also be needed to reach the higher end of the estimated range.
