Its impossible to make any kind of a determination on originality from that picture. We would need closeup of both sides and preferably the back sides of the lenses in order to make an educated guess. Value has a broad spectrum and any 2 collectors will have a different valuation on these artifacts. Most collectors use Scott Benjamins CD to do a general valuation and then they add or subtract from there. Good closeup pictures could get you an opinion from collectors on this page and it would at least give you a starting point to work from.
