Yard-O-Led fountain pen nib (not authenticated)

This is a close-up photograph showcasing the metallic nib and immediate grip section of what appears to be a luxury fountain pen. The visible elements include a silver-toned metal nib featuring an ornate, scroll-like engraving surrounding a circular breather hole. Stamped directly onto the surface of the nib are the capital letters reading 'YARD-O-LED', followed by '18 ct - 750', and the letter 'F' denoting the nib size. Just below the nib, the section collar or barrel ring displays a visible stamp reading 'STERLING'. The metallic surfaces exhibit a high-polish finish with rainbow-toned iridescence and slight patina or micro-scratching under direct lighting, along with traces of dark ink residue near the feed interface. The owner's supplied notes mention 'Yard-o-led 18k 750 F', an unverified user-supplied claim. The attribution in the item name rests on the legible stamped text visible on the nib itself, though this visual evidence remains unverified as to its absolute authenticity.

Based on what I can see in the photograph, I have evaluated the metallic nib and grip section presented for review. Per user submission: attributed to a Yard-O-Led fountain pen nib, the visible markings include stamps reading 'YARD-O-LED', '18 ct - 750', 'F', and 'STERLING' on the collar ring. I can't verify from a photo whether these stamped markings are contemporary to a genuine piece or if the component is an aftermarket reproduction, as surface markings can be replicated. Based on the assumption that the unverified user-supplied claim of an 18-karat gold nib is correct, comparable luxury writing instrument nibs of this type typically trade within a moderate secondary market range. The metallic surfaces show a high-polish finish with slight patina and micro-scratching under direct lighting, along with traces of dark ink residue near the feed interface, indicating prior use but generally sound cosmetic preservation. The estimated value range reflects the assumed identification, but would need physical inspection to confirm. If this item turns out to be a reproduction, replica, copy, or unattributed piece, the value would decrease significantly, likely dropping to the melt value of the gold content or a nominal sum for generic pen parts. To confirm authenticity and establish a more precise valuation, I would recommend in-person examination by a qualified horologist or pen expert, hallmark verification, and physical inspection of the material composition.
