I found this recently while sifting through a Kansas estate sale lot of mixed, loose foreign coins where I suspect it has languished for more than a decade. Regardless, given its excellent condition and modest mintage of 22.1m 28 years ago, it's well within reason that this coin's value is primed for aggressive growth.
In regards to the pictures, capturing the exact luster of any coin with a camera as it is seen by the naked eye is extremely difficult. These pictures at 2.5-4.0X magnification are not exact but a good representation of the actual coin even though many of the surface marks are highly exaggerated and not nearly as visible and predominate when seen in person.
Thank you for looking and please feel free to email me with any additional questions or requests.
